Perhaps they wanted to be unknown.

Please make VLB Virge! I second this. The only Trio64V+ card for VLB that I am aware of is the STB PowerGraph 64 Video. At least one member on VOGONS has one, but like you said it's possible that it's just a regular Trio64 card with an IC swap. I think one other company made a VLB card with 64V+, …

Working L2 cache. Very nice. Did you have to bridge traces on your CPU to get it working?
Re: Until when PC used 10 function keys, instead of 12?

I always hated the windows keys, and I still do. I held out a *really* long time. I think I finally got one in 2010 or so when I bought my first PC laptop. I had a friend who was really into the 84-key AT keyboard. He originally had one on an 5170 AT, and he carried it over to a 10MHz Everex 286, …

Probably 1985, possibly 1986. I believe that was when IBM introduced the model M as an option for the AT (model 339) and XT (model 086). They probably lingered on through the rest of the 80s, and there were people who preferred their function keys on the left side rather than on top, so you could …
Re: Pentium Overdrive PODP5V83 question
Posted on 2020-09-13, 09:06
That is a lot to overcome when running benchmarks. And surprisingly Pentium Overdrive is faster than classic Pentium 66, even with gimped front side bus. It's actually not too surprising...because when the P60 and P66 came out there wasn't proper memory or cache to handle the faster bus speed. So …
Re: DTX 486 DX/33
Posted on 2020-09-11, 15:29
The trick only works if I've owned the board for at least 25 years. Still, it could be a slightly different model. I know there is one fairly close that has a Weitek socket instead of a 487SX socket, but the exact name escapes me. Perhaps "FEAT-3331"? http://www.uncreativelabs.de/th99/m/C-D/33100. …

I can't see the entire board. But it looks like a PMK 0031Y. Interestingly it uses a DTK BIOS. This is the first time I've seen one with a DTK BIOS. They most often come with AMI HIFLEX BIOS.

I doubt the CD-ROM drive or sound card were original from the factory. The mismatched drives are not presentable for retail sale. I would also guess the 3.5" drive has been replaced. It's possible all of this was done by the original owner, but we haven't seen inside yet.
Re: DTX 486 DX/33

If the VGA card is oak, it's probably an ISA motherboard (without local bus). I would guess PKM-0031Y or a derivative.
Re: DTX 486 DX/33

I come from a DTK town. They were especially popular at the universities and high schools. I saw everything from XT to 486. My own DTK 486 had the 3.5" floppy drive in the vertical bay, not in an adapter (from the factory). My guess is that while they were transitioning to the baby AT cases, they …

82C84A is good for up to 25MHz. https://www.renesas.com/us/en/www/doc/datasheet/82c84a.pdf It's the CMOS version of 8284. I saw that, but I thought that was the crystal frequency, NOT the output clock frequency which would be / 3. So am I wrong? is that the actual clock frequency for the CPU? No, …

It's actually not that simple. Just about anything could cause the board not to post or beep. Of course, you should start in the most obvious places to rule those out first. In the worst case there could be damage to the silicon or PCB, which for most people means the board is not salvageable. …

Re: Cyrix 6x86L-PR200+GP or Intel Pentium 200 MMX?
Posted on 2020-09-02, 16:16
6x86L is an okay choice if you don't need anything that uses the FPU much, especially if you're going to run a lot of DOS software. Just be aware that it was kind of a budget CPU, so I would only recommend it if you want to enjoy the special experience of using Cyrix CPUs.
