Very nice !
I always loved that old tank mouse. It had less sharp edges than the Atari ST mouse.

Put my Dimension 8200 back in storage as I was trying to justify keeping where it was and couldn't and then Me farted out.
Didn't want to reinstall it as that's a PITA and I already have a 98 rig I'm happy with.
So into storage it went.
I've successfully installed an ISA FORMOSA MPB-000007 sound card. I don't know if that is the exact name of the card, but after some googling, I found working DOS drivers in Phil's web site for OPTi 82C929A ISA sound card. Since the card has a Yamaha OPL chip, it sounds great. I wish I had more knowledge about such similar cards (with OPL chip) a few years ago, instead I bought ISA Creative sound cards with Yamaha chip for a greater amount of money (although, I'm not sorry I bought them).
OPTi cards are underrated. Solid SBPro compatibility, genuine OPL3 (or a 1:1 copy sometimes), WSS mode for crystal clear 16-bit sound and drivers that are super easy to use and configure.
Whenever you run into a game that supports Windows Sound System (a.k.a. Microsoft Sound System), use that instead of SBPro for improved sound quality. You can switch between the two modes at any time using SNDINIT.EXE. No reboot required.
Took my old PC out of the box it had been in for several years, cleaned off some of the dust and cobwebs, put it together, but could not get it to work.

I have a near identical 82C929+YMF262(Clone) card in my collection and after some testing I found it to be not a great choice: It's SB Pro compatibility isn't reliable, sometimes only works well as SB2.0. It's also kind of noisy in older systems, and unless I had some bad luck it's also speed sensitive?

I have a slightly newer 82c930 model and it generally works fine in SBPro mode, except with Epic Megagames releases e.g. Jazz Jackrabbit, Epic Pinball, One Must Fall etc.
OPTi did release some fixes for that, and also for some other games which use older versions of HMI drivers. Look for EPICFIX.ZIP and HMIGAME.ZIP in the driver archive attached here.
Repaired a 9800 Pro. Had two Radeons 9800 Pro's each missing an inductor. Had nothing to lose, so took an inductor off the card with artefacts and soldered onto radeon card which stalls when 3d apps load. Got it working, happy! Stress tested and is stable so managed to save a 9800 pro

About two months ago, I got a Commodore PC20-III. It was the system and the monitor, in their original boxes.
This week I finally had time to have a good look, and to do something important...
Oh no, an unbroken warranty sticker! Still, I need to continue...
There she is... A barrel of death. Worse than an exploding barrel in DOOM.
Cleaned up, and had to bridge one corroded trace (and a via). I added pin headers so I can connect a battery later, but that probably won't happen.
Put it all back together, and she seems to work fine! I had to jiggle the motor axle of the HDD a bit to get it going, but it seems to work now. It's an XTA harddrive (8-bit predecessor to IDE/ATA). Quite nice to have it working.

Also sort-of-retro, since it seems I will be working at home for quite some time, I had to upgrade my home office/retro man cave a bit. I moved my work desk to a different corner in the room, and found an IKEA Jerker desk as a new work bench for the old stuff. I zip-tied a lot of power extension boards overhead, and installed a LED light bar overhead. Finally a decent workspace. The challenge will be to keep it neat and tidy...
IKEA Jerker desks were designed in the CRT era, so they have a lot of room, and are virtually indestructible.

Got some blue arrow keys (Desk Candy) for my Siig MiniTouch and put them on. Looks pretty neat. There's so many odd size Alps keys on this board, I'll never come across a full set of keycaps for this unless I have them custom made by Signature Plastics, so this will do for now.
Cleared out some hard drive space on the 4.3GB drive in my 386 as some games were too darn slow for the system anyway and I have about 1/2 the storage left, altered the CMS.DRV files for Sierra On-Line games, minus the VGA variants (added CMS.DRV 210 in the resource.cfg and resource.pq1 under soundDrv) and changed the batch file for Secret of Monkey Island and changed the HW address for the 3Com network card and soon the Aztech Sound Galaxy NX Pro (non-16) so that all of my games will work with the sound card this time.

Ah, crap. Had to perform some emergency triage on my IBM Thinkpad T21 - looks like leaving it on AC for the weekend to charge the batteries might've given it the infamous blink of death. Let's see if it comes back up to life within a day or 2 - if not, it might be time for a new motherboard.
Received an SN74LS158N chip that I ordered and decided to finally upgrade the RAM in my IBM XT/8088 build to 640KB. Following this guide: http://mail.minuszerodegrees.net/5160/motherb … ard_to_640k.pdf
My motherboard was a 64-256K board and had 256KB RAM installed, so I needed that chip first of all to install into U84.
I decided not to permanently modify the motherboard by soldering in a jumper, so did the quick jumper wire trick on U44 instead, which is easily reversible -
Then finally the RAM. I had a 2MB ISA "Parity RAM" card which I got for my 286 but could never get it to work - either the card had issues or more likely the motherboard wasn't supported (card was aimed at IBM 5170). So rather than let it go to waste, I stole 1 of it's banks of 18x 256K chips for my XT -
All working great, system now has 640KB RAM. Since I already had the RAM chips, this whole upgrade only cost about £3 including postage - bargain!
The old 64K RAM chips I'll put back onto the non-working RAM card for safe keeping.
256KB was limiting what I could run on this PC, now with 640KB I should be good to run anything that supports 4.77MHz & CGA. Going to start installing more games & software. Might even install Windows 1.0 for fun (could never get it to run on 256KB, even though it claimed to support it).
Also installed an Aztech Sound Galaxy BX II ISA Sound Card that I wasn't using. It's the only 8-bit ISA sound card I have and I thought I'd give that a try mostly for it's Game Port as I was previously using a 16-Bit I/O card just for it's Game Port, which was a bit of a waste as I can reuse that in a future 486 build instead.
I have been busy the last many weeks, moving in and getting everything set up. Today I finally had a chance of starting to build up my computing area. Nothing is hooked up, and I will most likely have to move stuff around. Anyway... One days work.

Thanks. The new place is good for me so far. It is liberating to be on my own again. However I have not had any time to do any vintage or retro activity as such so far. All the ordinaery stuff had to be put into place first.

You'll have the time for all your retro fun one the house is set up. I'm glad to hear all is well

Looking very neat, goob job.

This evening I've been getting this PS/2 to serial converter working but on a breadboard: http://trolsoft.ru/en/sch/mouse-ps2-to-serial
It's actually working 😀 I'm just testing with a Serial to USB adapter and my Windows 7 machine, but if it works here it should work on my 386.
Now maybe I'll put it together with solder. In the background, you can see Matze79's Ps/2 to serial adapter, which I haven't got working yet, I think it's the cheapy TTL>Serial converter boards I bought that don't work.
