I picked up one of these recently (ATX 20 PIN to AT P8/P9 Converter with -5V & On/Off Switch & Dummy Load) to use with a non -5V capable ATX PSU - seems to do the trick quite well!

My first PC was a generic AT Tower containing a 286/12MHz based board maxed out at 1MB, Hercules Mono Graphics and Screen (Green), a Genius branded mouse, a French AZERTY keyboard, a 1.44MB Floppy drive and NO HDD! I remember playing a lot with Dr. Genius, GW-Basic and running Sierra games from …

sure you don't mean a C-300A...? No, I do mean a Celeron 400A in a SEPP package - or at least, it was listed as such on my invoice. Back in the day people would refer to Mendocino Celerons as "Celeron A's" to distinguish them with the cache-less Covingtons, even though the only "true" Celeron A was …

In 1999 I upgraded my trusty K6/200 to a Celeron 400A with 128MB RAM. So it probably looked something like this: Celeron 400A @ 450MHz Abit BE6-II 128MB RAM S3 Virge 4MB PCI Quantum Fireball EL 5.1GB SB compatible? soundcard 10MB NE2000 compatible NIC I started with most of the hardware that was in …

@RacoonRider: sure, feel free to use the speedsys info! I'll keep the wiki in mind and will contribute to it at some later point 😀

Nice build! Cheap 15-year matured beige AT case (razor-sharp edges) Indeed, gotta love the retro feeling of having your hands cut open by just casually brushing against the case edges 😀 .. not!

Now that the build is complete, here's a SpeedSys report:

The system has received another upgrade. After some further testing, both AT Power Supplies in my collection were found to be unreliable. The 200W PSU had a tendency to turn off after 30 seconds when cold booted. The 230W PSU was just unreliable - which after 15 years is understandable. I've gone …

A new video card arrived in the mail today so the Trident card has now been replaced with a ELSA Winner 2000 AVI/3D (PCI S3 ViRGE/VX with 4MB VRAM). The ebay seller was amoretro (german), so Fabian, if you read this, excellent wrapping job 😀

Indeed, they are 82438s! For those interested, the manual can still be found online at motherboards.org

The system does not have cache soldered on the board, but had 256KB installed in the sockets, I obtained a 512KB COAST module, so I removed the chips and installed the COAST module instead. The system reports 512KB in cachechk 7.

Thanks all. In the mean time I also obtained (for free!) a Microsoft Sidewinder Precision Pro joystick with the serial connector, so another part that suits the era of this machine :) I still need to clean and test it though. @badmofo - indeed, the trident vga card is going to be replaced at some …

Hey all, this topic to present my brand new retro PC build. I wanted to (re)build an AT class machine again for some time now, and fate threw a donor PC in my path: - Modded Midi Tower AT Case with a 230W Power Supply - Pentium 100 CPU SX963 without a CPU cooler - Soyo SY-5TCS Motherboard - BIOS: …

I have a "spare" 80MB CP30084E that has entered its 20th year of existence - still works flawlessly 😀

Converted to AT using an ebay kit. Nice rig! Where did you find this kit, how is/was it called ? I see lots of kits to convert Power Supplies, but I can't seem to track down a kit to convert an ATX case. Would be fun to get a reference.

A hello from Leuven, Belgium 😀

Sadly this is the reality on eBay these days, people can't be bothered to read the offer and seem to think it's all fun and games and not to be taken seriously. You can log a complaint and recuperate the cost, but it takes a week to process - I've had a similar thing happen to me recently when I …
