Re: What is happening
Very good news for Kibby. I have a friend who has been a manager at an Olive Garden near us for years and she's had a good experience with them.

They want some willing to start at the bottom & work their way up to chef. Which is exactly what she wants. She'll be making a lot more money as well. They start everyone at 11 dollars an hour. She was making 7.50.

Way to go Kibby !!!!!!

Re: What is happening
Great news about Kibby. She's already shown her willingness to work in the past, so I hope that she moves up the ladder quickly.

Good for her I hope things go well.

Re: What is happening
That's actually a restaurant we've eaten at on one of our visits to the US. Really hope it's an improvement for her over the nonsense she's had to deal with before.

-- -- --

Decided to have a better shot at cleaning the Dynastart pulleys up on TPA.

There is deep enough pitting that they'll never be perfect, though I think this should be good enough for the job...given that the previous belts lasted the best part of a thousand miles and still worked once the tension was adjusted...if I go through £14 of belts once a year or so I'm really not going to lose any sleep over it.



Especially given they started out like this.


Sadly Motorserv only had one belt (Gates 6262MC for reference) so I'll need to swing by tomorrow to pick up the second one before I can fnish reassembly.

Re: What is happening
That sounds like a good advancement. I hope she has a happy work environment in this place.

Re: What is happening
Task number 1 today... changing rear spheres on the Xantia. Aside from knowing having it done will make the car far, far more pleasant to drive, I really want to get the sphere removal tool back to its owner. I'm utterly paranoid about losing other people's tools so always try to get them back as soon as I can.

Dodged the usual game of chasing the ramps around by doing the job on the lawn. They dig in enough there to stay put.


Still hate getting the car onto the ramps.

Of course because it's the Activa there's a hydraulic line in precisely the right place to be in the way when you're trying to get the removal tool onto the sphere.


Not enough to be a problem, just enough to be moderately annoying.

Offside one first, wound off without too much of a fight


Only slight game I had there was the seal vanishing into another dimension (I did find it eventually) which had me second guessing if I'd got the old one out of the strut for a few minutes.

New one in. That's this side done.


Nearside required a little more persuasion to shift, but I was still able to do it by hand just using the sphere tool. Didn't need to get any additional breaker bar or anything involved. It's really nice working on a car where the previous owner or a garage haven't overtightened absolutely everything.


New sphere on.


Tightened the bleed screw on the regulator back up, checked for leaks then that's that job done. Maybe 20 minutes?

Well it would be if the new spheres weren't flat. Knew it was a bit of a risk being NOS ones from 1998...but was worth a shot. Offside one is passable, nearside one though is just as bad as the one that came off.

No huge inconvenience really, as mentioned above they take about 20 minutes to change and they were given to me free, so I'm really not even in the slightest irked by this development - it's just one of those things that happens when you're tinkering with old cars and old parts!

We'll be playing this game again shortly then.

Second new belt was picked up for TPA today so those have now been fitted. Adjustment seems spot on with the six spacers split evenly with three on each side.


The bit of trim that I re-stuck to the offside door appears to have remained firmly attached overnight - so if I have any more bits coming adrift I know going in what approach to use - basically loads of adhesive.

On the subject of trim, while getting the whole roof lined is definitely a job for "sometime in the future" one bit I really wanted to address was the rear C pillar on the offside, mainly because of an unsightly historic repair there.


Conveniently I had a couple of offcuts left from when I did the carpeting job which I was fed up of shuffling from place to place in the garage. They were just big enough to do this.


Far tidier!

Obviously made a matching one for the other side too.


Have left them both wedged in place while the glue sets. I'd really like to replace the windscreen demister duct, however it's still a way down the list - especially at £25+ a metre!

Zelandeth Apr 25 2021 06:47 PM

Re: What is happening
Nothing much to report from this weekend, though I did finally get around to giving the Jag a wash this afternoon. The amount of gunk that was accumulated around the window seals and such like was frankly embarrassing.

It's definitely one of the most awkward cars I've ever had to clean - especially the front and rear overhangs. Doesn't scrub up too bad though from ten paces.



Hoping to get the van in for an MOT this week to find out if there's any work needed for that I'm not currently aware of (expecting a shock absorber and a couple of brake pipes as the ferrules are rustier than I'd like). Have had a couple of recommendations for a garage to use (my usual one can't deal with vehicles this large) so we'll see how that goes.

Zelandeth Apr 26 2021 07:00 PM

Re: What is happening
Later this week I've got a couple of portable split system air conditioners to collect. I reckon that I *might* just about be able to Tetris both of them into the back of the Xantia...maybe. I'm quite braced for having to make two trips though. At the end of the day it's only an hour each way so if I need to make to trips it's hardly the end of the world. However if I had the van available that would make things far, far easier as I'd have bags of room to spare then.

Following a few recommendations on the MK Modern Classics group on Facebook, I've got it booked in with MOTest in Newport Pagnell on Wednesday morning for a test. My usual garage can't do me an MOT on this as it's too big and too heavy for their test bay.

I've been out and given her a quick once over. The brake hose ferrules are a bit more crusty than I'd really like. I wouldn't say they're bad, but I'd definitely expect them to at the very least to be an advisory. They'll be getting changed either way - just not before Wednesday.


Still slightly irked that the garage last year didn't even get a mention last year given the number of as far as I can tell non existent faults with the braking system that they found and charged me for sorting...Would have expected the rigid lines to have got a mention too - though those at least just need a clean up I reckon.

The front shock absorbers, particularly the offside one look quite crusty (and it has a dust cover held on with a cable tie), but they both work as far as I can tell. Like the brake flexible lines, I'm going to plan on swapping those out in the near future anyway for peace of mind.


I've sorted the spurious brake pad wear warning light issue - by disconnecting the sensor leads. I'm not proud of it, but the problem is a simple fundamental issue with the system design which results in false triggering with modern brake pads. Rather than the way for instance BMC did where they just have a light in series with a metal tab in the brake shoe, which grounds the circuit through the disc when the pad gets worn down, Mercedes have the switching done by a transistor - meaning that even the tiniest bit of leakage to ground at the brake end of things brings the light on. I don't think I've ever actually seen one of these vans where the wiring wasn't snipped off decades ago... guessing this may be why! I've not cut anything, no need to. There are two connectors that can be unplugged in the engine bay. So if somewhere down the line I feel like modifying the system to be less hyper sensitive I can easily get it going again. Though being honest on a van that's doing a couple of thousand miles a year it's really not necessary. Obviously would be far more important a feature if she was a van in heavy commercial service doing thousands of miles a month!

Discovered the nearside indicator repeater was out. This turned out to be a bit of poor design. The ground for the repeater is via the mounting screw - however that's just a self tapping screw into a plastic plug on the inside of the wing. A bit of rust on the screw where it passed through the wing = dead light. I've done away with that and replaced it with a nut and bolt with a shake proof washer, and a big blob of grease over it to keep water out.

There could be a thousand things I've missed though...it barely moved last year. Obviously being an old Merc rust is the biggest fear!

I then went and cleared what felt like about two tonnes of dead leaves and dog hair out of the interior.




I'll get back under there tomorrow and give all the rigid brake lines a rub down and see if I spot anything else needing attention. I will say it's really nice having a vehicle that you can comfortably work underneath without needing to faff about with jacks or ramps! In the interests of seeing off Murphy's Law, I do stick an axle stand under the chassis rails though just in case a spring decided to snap while I was crawling around under there. Unlikely? Yes. However I know my luck and it takes all of thirty seconds to do. So let's just play it safe.

I'd by absolutely lying through my teeth if I didn't say I that even just on the run to the testing centre that I was massively looking forward to driving the old bus again. It's been far, far too long. I do find it highly amusing the degree of decision paralysis that I sometimes suffer as to whether to go out driving in a Citroen Xantia Activa, 2.8 tonnes of camper van with 78bhp, a V12 Jag XJ-S, or an Invacar. I enjoy driving all of them...Though honestly the Invacar probably has caused the biggest grins from me lately.

They all have their moments though...

Xantia: Seeming ability to totally ignore the laws of physics where changes in direction are concerned and the addictive shove in the back when it comes on boost.

Jag: The sheer degree of torque from a standing start is absolutely ridiculous...oh, and the noise when you go anywhere north of 3000rpm. Comfort goes without saying...and the looks.

Van: She's just a lovely old thing to drive. Gearchange, steering, ride and strangely enough, the smell all say vintage bus to me.

Invacar: Hard to point at any one thing, as it's just such an utterly unique driving experience...and far, far more capable a vehicle than you'd ever think to look at.

In other fleet news, for the last month or so I've been unable to get the boot on the Xantia unlocked. Wouldn't unlock with the central locking or the key. No amount of fiddling around with either on a dozen or so occasions had any effect. Yeah...right up to this afternoon when I went outside to properly investigate and fix it.


When I unlocked the car to undertake this task the bootlid unlocked perfectly normally. The lock has then proceeded to work absolutely perfectly, and pulling the trim off didn't reveal anything amiss which would have caused any issues. Yep, that's pretty much situation normal then!

Got a new car today. A 2021 Honda Accord Sport 2.0 (turbo) 4 door sedan. It is a metallic blue with black fabric seats. I'll have to get used to not putting a key in an ignition but heated seats sounds like a nice luxury. I have no way of putting pictures here any more, you'll just have to imagine it. :)

She had orientation & worked her first shift. So far she lives it. She has several choice of food can get free. Ever year the company sends several employees to Italy to attend their colanary school. She is hoping she can go. All general manager have to go.
She will get 2 hours added pay once she has her second shot. They schedule you 2 day off after getting the shot
Which is good she selp for 2 day. Was feverish & her arm was very sore on the second day.
She likes the people sh worked with. From what she is telling me, the company is a good one to word.

Thanks R'zil, I was wondering the same thing. I've been thinking there's a different link we should be trying because the one I've used for quite a while sure isn't working.

Re: What is happening
Little been going on lately really as sadly boring responsible adult homeowner tasks have been keeping me very busy.

A little package arrived this morning though.


Lovely little IBM branded calculator paperweight. I wasn't expecting to win this to be honest as IBM memorabilia usually goes for silly money. Quite possibly because the calculator was dead so a static exhibit. I didn't really care either way as it's an interesting bit of desk furniture anyway and will look great next to the IBM keyboard (which is one of those bits of technology I can't ever see me replacing).

Oh...and one turned up on Saturday too. That was another £0.99 starting bid item that nobody else bid on so was less than a fiver delivered, so an Imperial 91S has also joined the calculator collection.


I don't have a problem...I can stop any time I want!

Of course being me the calculator built into the paperweight wasn't going to be left as a static exhibit if I could fix it was it? On removing the cover it was obvious no batteries were fitted, replacing those though did nothing so I pulled the board out.

Can you see anything wrong here?


Yes, that is indeed the front display polariser. Behind the display. Well that's not going to be helping anything is it. Sorted that out, cleaned the inside of the display window and put it back together and...



Have to wonder if that's a manufacturing defect and it's never worked since it left the factory in May 1984.

Tell you what though, by mid 80s standards it's a *slow* calculator. All 9s divided by 1 takes a good half a second. That's mid 70s territory! Guess that's the price paid for something so cheap as to be built into promotional novelties like this.

It's a lovely thing though and given I do tend to have a window open or fan in use a lot a paperweight is honestly something I'd been meaning to add to my desktop for a while.

What answer does it give to 0/0? ERR? Or does it cycle through the digits trying to reach infinity?

I had an early Sinclair Cambridge that used to do the latter till it ran out of battery.

Re: What is happening
Here is a question for you, Zelandeth. We recently bought a new Honda and it came with "wheel locks." However, my husband wanted better ones and researched a company in Sweden called "Rimgard". He has ordered a set and plans to install them. Apparently there is a problem in the US of thieves stealing nicer alloy rims and reselling them. Do you have this problem in the UK?

Surprising to hear that to be honest. It's not something I've been aware of being anything like an issue over here for a long time. It was more of a thing here when alloy wheels were an expensive optional extra...but since even basic city runarounds come with them now it's just not that much of an issue.

To be honest the first thing I always do with any car that comes with locking wheel nuts generally is chuck them in the bin. Far, far, far too many have keys which just aren't up to the job and just end up with you unable to get the wheel off when you have a puncture. I've had to help far too many people deal with lost or broken locking wheel keys to trust them.

If someone really wants to nick your wheels it's not going to make any odds. The thieves will have all the standard keys in their car and the equipment to get around them if they don't.

This will just show an error in that situation. I don't think I actually have any calculators which are early enough (or with shonky enough algorithms...Sorry Sinclair) not to catch a divide by zero. Have a few which will happily give a result for a square root for negative numbers though.

So far Kibby LOVES her job. Even Mother's day was not bad. They were, of course, very busy. Kibby didn't mind, she didn't have to deal with customers & Oluve Garden bought pizzas for everyone. So she was happy.

Priscilla May 13 2021 01:02 PM

Re: What is happening
It sounds like a very good place for her. Best of continuing luck!

Last night we went to our first indoor "musical" performance in over a year. The high school where our daughter's boyfriend is the choir director/musical director put on Little Shop of Horrors. They had about 1/4 of the auditorium seats filled, everyone wore masks. The actors had body mics and wore clear plastic masks. After having to cancel last year's show it was wonderful to be back! :good: They have 5 more performances, ending with a matinee on Sunday.

Re: What is happening
Really glad that it sounds like things are working out better there for Kibby. Even little things like them buying pizza for folks after a busy evening really do make a huge difference to how it feels to work for a company I think. Long may that continue!

-- -- --

Have had some quite major progress on one of my longer term historic computing projects though.

One of my favourite machines out of all those I've owned over the years was an old Toshiba T1200. An 80C86 based portable dating from 1988. I found it to be a really genuinely useful productivity machine, with a nice keyboard, form factor which made it actually easy to travel with, and a battery life which can put many modern laptops to shame. Sadly this came to a shuddering halt in mid 2002 when the power supply board developed a fault. Didn't take long to figure out that all it needed was replacement of a couple of capacitors and a good clean. Unfortunately due to a communication breakdown between me and my parents while they were doing a clear out, several key components were lost. The remainder was stuffed in a box in the hope that I could get back to it one day. Particularly of note was that I really wanted to recover several documents off the hard drive (I was young and stupid at the time and didn't have a backup regime in place), which meant getting this or an identical machine up and running as the hard drives are of a non-standard type so I can't just plug them into another computer.

Note the strange 26-pin interface connector.


It was then largely forgotten about for a good few years, until about ten years ago when I started to get back into the hobby of messing around with old computers. Unfortunately I discovered at this point that these machines are actually quite sought after, and the issues I had with the power supply in mine turned out to be one of those faults where it's a matter of when it happens rather than if it happens...as such working examples swap hands for several times more than I was willing to spend. Non working or those claimed to be untested seemed to have their pricing rather more determined by a random number generator.

The big problem with buying a machine that was non functional or untested is that the nature of the fault means that it's a complete lottery as to whether the machine is repairable, a good parts donor or nothing but a door stop. This is the power supply board used by the T1200.


By the standards of 1988 for a power supply board this is quite a complex bit of kit. That's because in addition to providing the voltage rails needed by the machine (12V, 5V - all normal there then, but also -9V and -22V more unusually), this board also does all the battery management and has direct control over power to the hard drive, floppy drove, internal modem (where fitted) and the display. It also interfaces with the screen closed switch to give the ability to suspend the machine state - which we take for granted on laptops these days, but in 1988 that was a truly cutting edge feature. One of the reasons that this thing was quite capable of getting north of 7 hours out of a charge with a bit of care on the part of the user.

The problem with these power supplies is with those electrolytic capacitors to the right of the board. Once they get to a certain age they tend to become physically leaky. In the short term this isn't a huge issue...It causes the power supply to trip out into a protection mode meaning that the machine won't work (you just get a flashing red status light) as it can tell something is amiss. The big problem however is that the electrolyte which leaks from those caps is corrosive, and if the board is left in that state (and when these machines stopped working they tended to just get stuffed away in a cupboard or loft and forgotten about) this causes the traces on the PCB to be eaten away. A pretty typical example of this is shown below. That photo is actually of the underside of the board...the traces on the top layer tend to fare even worse.


It would *probably* be possible to repair this...however I've never been able to find a schematic and layout diagram for the board so you'd need to reverse engineer it first. Trying to do that with half the traces and three quarters of the through board vias having dissolved is a bit like trying to do a crossword puzzle backwards while wearing a blindfold and a pair of boxing gloves. The *biggest* problem though is that due to the location where the corrosion tends to start, the first traces that usually seem to go are the output side feedback lines...meaning that when someone plugs a machine that they've just found in a box somewhere into the mains, the first thing that happens is that the output voltages from the power supply shoot sky high...Usually resulting in every chip on the motherboard being nuked about five seconds before the switching transistors in the power supply itself take exception to the situation and expire in a puff of acrid smelling smoke. Even figuring out what those are to replace them is a chore in itself as they seem to be stamped with only a Toshiba internal part number which doesn't match anything else anywhere. So you've quickly gone from a machine which needs £15 worth of capacitors and an hour's labour to sort...to a half dissolved, blown up power supply and a motherboard which is now a doorstop.

It's because of this situation that over the last couple of years I've ended up accumulating three parts machines in addition to the 3/4 I still have of my original one. The most recent of which arrived last week.

This was described by the seller as broken, with the light on the power supply initially being green when plugged in, but turning to flashing red as soon as the power switch was flicked. Having a pretty good understanding of how these machines work, I knew that was actually a VERY good sign. These machines don't like running without a battery installed - tending to trip out during high power events (such as the hard drive spinning up) if one isn't in place. If the supply had failed catastrophically and nuked the whole machine it would either do nothing or show a solid amber light (which isn't a valid state)...so the odds were that the PSU board in this machine was either working or in a state where it could be saved. The rest of the machine was missing a couple of bits here and there but nothing I didn't already have spares of.

Obviously the very first thing I did was pull the board out for examination and testing (which takes all of five minutes...oh how I wish modern laptops were this service-friendly!). Initial signs were very good. This is the area of the board which usually suffers by far the most badly.


I'm not entirely certain if these caps have just started to leak or if the grime on the board was just generally there from the fact that it's 33 years old (there is a small vent grill above the power supply in that area). However they're obviously going to be changed (along with every electrolytic cap in the entire machine) as a matter of course. After giving the board a good clean I did a bit of testing, sure enough the expected voltages were present in the expected places.

After a bit of head scratching I managed to figure out an arrangement where I could make all the necessary bits of wiring reach to allow me to do some testing without reassembling the case...and when powered up we got life on the screen showing that it was at least trying to work.


The hard drive that was actually in the machine at that point wasn't interested in working. It simply went "click" once and that was it. While having that drive working would be nice, I had another from the previous spares machine, plus the one I was really interested in was the one from my original machine. The other spare was successfully spinning up but kept shutting down again during the initial seek operation - it allowed me to confirm the right supply voltages were present on the right pins though and that I wasn't going to immediately fry my old drive by plugging it in...so it was time to do some testing of that. I had the camera rolling for the event. I had no idea whether the thing would even spin up, much less whether we'd be able to actually read data from it.


To my considerable surprise it spun up and worked absolutely fine on the first attempt...No untoward noises, no protest...just worked. Since that video I've managed to coax both of the other drives back into operation as well, though the one is still a little cranky about starting.

I had no memory of setting up a custom boot screen and a little system description that prints on the screen above the command line at start-up...but apparently I did! It's astonishing the things you find when digging through a drive you've not been able to look at for 15 odd years.

It was obvious though that something was amiss with the display...I had a *serious* lack of contrast.



I knew this wasn't right as I remembered the display on this as being pretty decent. A bit of examination quickly identified that this is a physical problem with the actual display itself - however I do have two good spares. Looking at it next to one of my spares it was really obvious that there's something wrong with the original panel. The "off" state of this display is dark, so in an unpowered state the display should be a uniform deep indigo colour - like the lower one in the photo below. You can clearly see how much paler the top one is, with the tan colour of the unlit backlight showing through.


Thankfully swapping the panels over on this - as with most parts - is a quick and simple job. The difference compared to the earlier photos is clear as day. While the response time isn't anything to write home about this display really isn't bad at all to use. Contrast is very good, viewing angle is fine and the backlight is more than bright enough in shady areas. When you're in an area with lots of light you can basically turn it off thanks to the nature of the screen.


At this point I put everything back together and set about copying the documents I wanted off the hard drive.


After that the system was depowered and everything unplugged. It won't be going near power again until such point as I've had a chance to replace all of the capacitors. Given it's taken me so many years to get to the point of having a working system again I'm being very cautious with regards to not doing anything stupid that might cause issues. Once the caps have been replaced there should be no reason that the system can't be put back to work.

I also gave the case a good clean. I may well transplant this into the case from my original machine as it's far, far less yellowed than this one is. That is if I can *find* the upper case moulding in the loft. I knew which box the innards were in...not so sure about the case! Sorting the loft out is a job on my list closely behind "sort the garage."



Another reason I'd like to swap the cases over is that the legend on the indicator lights above the keyboard clearly shows that this upper case half came from what was originally a dual floppy drive model which had the hard drive (and controller card) fitted at a later date, as it shows drives A and B on the legend.


Whereas factory hard drive equipped models have this legend showing A and C, like this.


Minor detail, but it would be nice to have that right if possible.

The battery in there is from the second parts machine which had obviously spent much of its life sitting next to a window and has one of the worst cases of yellowing I've seen! Despite dating from 1988 though that battery pack still took a charge!


While the capacity will no doubt be vastly reduced compared to its original figure it was still able to run the machine for more than the 15 minutes or so that I had it on test for. It shouldn't be too difficult to open this pack up carefully with a Dremel or similar and rebuild it though, if memory serves there are 6 2/3AA sized cells in there - and I've got a few of these packs so don't mind potentially sacrificing one in the interests of seeing how hard it is to rebuild. Having a useful battery life though is something I'd like to make sure this still has to offer though.

Just waiting on the capacitors to arrive in the post so I can give the machine a blanket cap replacement then it can be put back into use...and to have a bit of fun testing done on it. I know about and have a lot more DOS software in the library these days than I did back in 2002.

Feels like I've finally made some good progress on this one after ten years of false starts, setbacks and frustration.

Re: What is happening
Really not much to report, though despite the weather I did manage to get TPA out for a run today when I had to go out and collect a couple of things.

Once more making normal modern cars look comically huge.


I need to take a look at the idle adjustment as it is definitely a little on the high side. Not sure if the throttle cable just needs a little more slack in the adjustment or if the idle screw on the carb actually needs adjusting. It's one of those things that I keep remembering every time I have the car out, but immediately forget to actually get as far as doing when I get back home.

Re: What is happening
Last week we had the little T1200 in a more or less functional state. There was quite a bit of noise on the screen now and then which I really didn't like, but I was at least able to copy the documents I'd been after off without incident. With the new capacitors in hand though it was time to see if they could improve matters.

So started what was without doubt one of the most annoying repairs that I'd faced for a long while. There were a few contributing factors.

[] The component density on the back of the PCB is such that this is really stretching the limits of how tiny traces I can deal with without a proper magnifier and kit to hold the work piece on the bench.
[] The tip on my soldering iron is absolutely shot...I have finally caved now and ordered a couple of replacements.
[] One leg of several caps is tied to the internal ground plane in the PCB which was acting like a giant heatsink and making it very difficult to desolder those pins - especially with a soldering iron with a stuffed tip.

I eventually opted to snip off the last few caps and just solder the new leads onto the stubs of the old ones...Which would have been far easier if I'd been able to find my good pair of side cutters. Of course I *couldn't* find my good pair of side cutters so had to resort to wobbling the caps back and forth until the leads fatigued and snapped.

The resulting hack job is without exception the most downright horribly ugly repair I've ever done. Though when I go through this job again in future I'll have a better plan going in, will make sure I have the tools on hand and also ensure that I actually have a decent tip on the iron. I reckon I could do a far, far tidier job in about a quarter of the time in future. I'm honestly ashamed enough of this one that I really don't want to show it! If the supply proves reliable I'll go back in and tidy things up a bit and add some support for the caps which are now sitting quite proud of the board.

Taking a look at the display backlight inverter board I don't think leaves us with any question as to why that was fading out over the course of a few minutes...


I think that this one falls under the "caught it just in time" category given it was still functioning. With a thorough clean and a new set of caps I reckon this will be fine as a spare. Thankfully the inverter board in the spares monitor was mounted the opposite way up (no idea why!), so the leakage there hadn't touched the board, just left a stain on the inside of the case. So I stuck a new set of caps in that board and swapped them over.

Somewhat to my surprise when powered back up I had all the correct voltages present on the output terminals of the board (the -22V rail was actually showing a far better value too, it was only showing around -18V before, which I reckon is why the screen was struggling), and when hooked back up...


Given what a messy job I'd done of it I was honestly quite surprised that it just worked properly. It was immediately obvious that the display was a lot happier too, I'm guessing the -22V rail struggling before was upsetting the bias voltage for the LCD.

It's quite interesting comparing the new capacitors being installed to those which came out, the fact that insulation technology has come on a fair bit since 1987 really does show in how much smaller some of the new caps are than those they replaced. In the photo below the new caps are to the left of those they replaced.


I had mistakenly thought this machine had failed just before I finished secondary school, but the contents of the documents folder suggests that it made it into the first couple of months of my time at university too. Though reading some of the notes I'd taken there did a good job of breaking my brain a little - it doesn't feel like more than a year or two back that I was taking them...Definitely not 19 years ago!

I wanted to keep the machine up and running for a few hours as a stability test...Not hard when I discovered that all my Sim City saves had indeed survived.


Well there went a couple of hours no problem! Probably looks a bit strange to people being in inverted blue on grey...but given how many hours I spent playing it like this seeing it in colour looks odd to my brain.

Back when I was using this machine as my "daily driver" I didn't have all that much DOS based software to hand. It was pretty much just VDE as the text editor, Sim City for when I got bored, and for reasons I can't quite fathom I had an image viewer on there as well...which on a mono inverted LCD screen is about as much use as a chocolate teapot...My guess is it ended up on there purely because I apparently got it in my head one day that I wanted to create a customised graphical welcome screen to show when the machine started up. Beyond that it was just a bog standard OEM MS-DOS 3.30 install - only interesting add-on I'd found was the program for setting the BIOS options...all eleven of them! Useful though as without this there's no way to enable the hard-RAM and suspend features, which I made plenty of use of back in the day.


While this did everything I needed it to at the time, something I was acutely aware of being absent was anything whatsoever in the way of software to keep tabs on the health of my hardware. Something I was easily able to rectify today though. I've always had good luck with the Norton Utilities suite, so chucked that on there. This was obviously the result we were hoping for from the hard drive health check.


Glad to see the surface test come back clean despite the 19 year hibernation.

Also meant I could interrogate the system with the information tools to see what they had to say.


Not exactly a speed demon...but with a 9.81MHz 80C86 you're not really looking for performance!


Might be interesting to do an actual performance comparison at some point between this and the Amstrad PPC512...

I've only got one other hard drive which uses a stepper motor based head actuator, and it's a good deal slower than the one in the T1200, especially where seek times are concerned.


Though this result only really counts when the drive is "awake." After about five seconds of idle time this drive automatically parks the heads - which given how fragile drives of this era were, and with this being a portable machine is honestly a very sensible design choice I think. The downside however is that it takes a good half second for the head mechanism to unlock and get the drive back into read/write mode. Realistically, do you notice? No. Absolutely worth a bit of a performance hit...I'm pretty sure this design choice is one of the main reasons that this drive has so few bad sectors on it - about 20K's worth, which is an order of magnitude less than the other few drives I've got from this era. Latency was never going to be a huge strong point of this drive anyway given it only runs at 2650 rpm.

Given the relatively slow seek performance of it being a stepper motor rather than voice coil actuated head in the drive, defragmentation can (and does) really help with performance.

Here's some audio that should be a blast from the past for folks who used machines like these back in the day - that drive getting a good old workout while being defragmented.


I remembered something quite abruptly a couple of days back when backing up my old files...That file management from the DOS prompt is downright painful. Easily solved with Microsoft MS-DOS File Manager...which I'm not quite sure why wasn't just bundled with DOS back then as it makes things so much more usable.


It's basically the DOS Executive from Windows 1 & 2 sans some of the graphics - even has a dedicated menu you can save shortcuts to commonly used programs/commands in.


It's basic, but does what I need, and is all of 70K...so far I've not come across anything it won't run on.

With the machine having been running all evening it had been absolutely stable. The power supply was barely even warm - so the running conditions have definitely improved as it used to get really quite obviously toasty after half an hour or so.

Need to have a dig around and see if I can find anything else interesting to run on it...though to be honest I've got everything I actually need for it to do what I want it to now.

Last thing I wanted to look into was the battery situation. I've got two packs which appear to be taking a charge - but they're obviously not going to have much capacity left. I did have one that was as dead as a door nail though...An ideal candidate to be sacrificed to find out if they can be rebuilt.


These packs are 7.2V NiMH units rated at 2200mAh. Annoyingly they're sonic welded shut...However I have a Dremel so that took all of a minute to get around.


Chunky cells! Looking at them though, no surprise this one isn't charging.


A bit of investigation revealed that they're bog standard C size cells.


Well isn't that convenient? A quick look at Google seems to suggest that the going rate for NiMH C-Cells these days is 4000-5000mAh - so with modern cells in here we should be able to more than double the original battery capacity. Let's just remember...I was getting through a full day on the original batteries back in 2002 when they were 14 years old...We should be able to comfortably get 10+ hours on a battery out of this thing. Not bad for a 33 year old laptop.

Probably won't see a huge amount more of this thing now it's been officially revived (unless you want to and/or have anything you'd like me to try with it).

Amazing Zelandeth. I wish I had the skill to resurrect a few of my old devices, but the modern ones work for me, for the most part.

Thank you. I'm sure we will enjoy it.

Do you or anyone ever hear from Lady Maelin, that wonderful artist who did the beautiful Pern artwork? I lost touch with her 5 or 6 years ago and was hoping to hear she is well and still creating!

Zelandeth May 23 2021 06:14 PM

Re: What is happening
Remembered the keyboard shortcut to get to the "fuel gauge" for the battery - function + sys req.


Also figured that this might be an interesting experiment.


Windows 3.0 is the last version that would run on an 8086/8088, albeit looking a bit strange on an inverted monochrome LCD with a bit of an oddball (640*200) resolution.

Runs a lot better than I expected to be honest. Bit sluggish when waiting for disc access but that's expected really.





To be honest I'm not really likely to use Windows for much...the MS-DOS Manager does a decent job of file management and all of the software I really need is DOS based anyway. I was mainly just curious to see how it ran on an 8086 machine.

Think the display really does show how it was really designed with text based applications in mind. It's not at it's best when dealing with graphics - but does a surprisingly good job of text. To be honest it's a lot more pleasant to use than the DSTN panel on the mid 90s ThinkPad I've got. Which is just utterly "meh" whether displaying text or graphics.

Replacement tips finally arrived today for the soldering iron so hopefully future work requiring it will be somewhat less frustrating...I really hadn't realised how knackered the old one was until I started doing delicate work with it!

Few folks have asked me what iron I use elsewhere, same one I've had for about fifteen years now.


Iroda Solderpro 120, little gas unit. It's not as precise as an electronic one where you can dial in an exact temperature but you can very the power from virtually nothing through to about 100W, which has done everything I've asked of it so far. Using an electric iron with a cable in the way always feels really cumbersome once you're used to a gas iron.

Speaking of tools, I finally stopped procrastinating about it today and picked up a new lawn mower.



Initial impressions are that it feels well made. Quite a bit bigger than our old mower, will be curious to see how well it works - given that the old one was a kerbside find that cost me all of about £3 to get running it owes me nothing. It could be repaired - but has just got to the point that enough things need doing that it's just not worth it when there's something I really can't fully resolve - and that's that the grass collection box is missing. I've tried half a dozen times now to buy a new one but just haven't been able to get hold of one - so given it needs new rear wheels, replaced wheel bearing on one of the fronts, a couple of missing bolts replaced, ideally a new drive belt and a couple of cracks in the deck that are starting by the handle base repaired...it's just not worth it. Nothing wrong with the engine though...so I need to see if I can come up with something to do with it...current thought is "I wonder if I could find a suitable pressure washer pump head to hook up to it..."

Given the weather forecast over the next few days goodness only knows when I'll get to do the first test!

Bristol May 24 2021 05:52 PM

Re: What is happening
LOL... Windows 3.0. My first experience with Windows way back when. Since I found a source for Window 1 and 2. They ended up with Windows for Workgroups 3.11 which is the only one that makes sense if you are rebuilding old hardware. But dos works quite well (and in many cases) better without it. I have a couple of old Dos programs. I have Word Perfect 5.1 for Dos.

Soldering is not among my skills, although I can do a fair job of troubleshooting computer components on 486 and up. Used to do it for a living.

Zelandeth May 24 2021 09:01 PM

Re: What is happening
Despite the weather I managed to get TPA out for a run today.


Contrary to what it looks like in this photo there were very ominous looking storm clouds just out of frame to both sides and behind me.

Never ceases to put a smile on my face this little car, really does drive far better than she has any right to.

Still not quite how I managed to dodge all the worst of the weather...it was all around me pretty much the whole time.

P'ter May 25 2021 06:38 AM

Re: What is happening
Priscilla: check out Linda Martin Eicher.

Windows 3.11 was not bad but CAD programmes etc. had to run under DOS given the limits on Windows file size.

Zealandeth: if you want another odd car; try the Metro Chairman conversion.

Priscilla May 25 2021 09:21 AM

Re: What is happening
P'ter, I have done that. I used to have her on Facebook but she may have stopped using it. I had a snail mail address which I have also sent her notes at. Asking if anyone here has heard from her was my last resort.

I used to see those tiny cars when I was in England in the early 1970's.

Re: What is happening
I wish I could send you some gasoline. I've seen pictures of people hoarding it in plastic bags and all sorts of other dangerous containers. Then, there have been the vehicles full of "containers" that have caught on fire. Is the supply getting any better?

How is Kibby's job? Does she still like it?
