I have an m918 motherboard. It came with cache sockets. I was able to "use" 1024K of cache, but don't expect much from it. On this board, when you have set the fastest RAM timings, the cache results don't appear on speedsys or cachechk, even when the cache settings are set to the fastest in the BIOS …

Feature-for-feature, the Intel 486 DX4 write-back 16K is a little faster than the AMD 486 DX4 write-back 16K. The only systems I have setup with Intel CPUs are those which cannot use other processors, like a dual slot 1 and a dual socket 370. Retrospectively, I find it far more interesting learn …

Did many people really enjoy playing Quake in DOS at 320x200? Looks pretty miserable to me. Then when you shoot up to 640x480, the framerate on a P133 is only 13 fps. For this to play well in DOS at 640x486, seems to me that you really need to use a CPU that is not quite period correct, at which …

POD 86 will run games like quake the best (due to it's FPU performance), but not at frame rates that I would consider enjoyable enough to bother anymore. Do you not consider a POD83 at 34 fps, or a POD100 at 41 fps playable in GLQuake? https://www.vogons.org/viewtopic.php?p=697548#p697548 It was …

So you weren't able to find a PDF datasheet? Because my first thought was 256Kx4. But if it is 256Kx8, then that's a good amount of DRAM for an old ISA card.

This is what I see: E1 and E2 2x KM416C256J-7 and U10 thru U17 8x MT42C8254DJ-7 You are saying that U10 thru U17 are 256Kbyte each? And if so, how do you know this?

Why doesn't the chipset show S3 on it? Was S3 called something else back then? I couldn't find the datasheet. How do you know it has 2 MB of memory?

There seem to be two prominent serial cable wirings found on computers os this general era. Best to keep a few of each around for testing. As a very general rule, it appears as is SiS 496 boards often use the same standard while UMC 8881 boards use another. I find this odd because the RS232 chip is …

I'd like to see if there is any difference between the WinChip, Winchip 2A, and Winchip 2B at the same FSB and clock rate. winchip2 is far better than winchip and comes close to k6-2. winchip2a is simply winchip2 updated to support higher fsb and fractional ratio, winchip2b is updated with newer …

Yes, you read that right - I write SSE and not SSE2. There was a point, perhaps around 4 years ago, at which running Windows XP updates on my AMD K6-III-500 and Cyrix MII-433 systems caused it to no longer boot. I had to restore these systems from backup clone HDDs. Does anyone know what the dates …

I'm sure you can find one of these from any piece of dead hardware and solder it on. This adapter is so cheap that such difficiencies don't bother. This is …
