If the 8087 has a later date code it will probably overclock. Just be aware that all 8087s were based on 3 micron NMOS designs. Because of the way the 8087 is interfaced to the 8086/8, if your FPU overheats it will crash the CPU too. 8087 is probably one of the worst chips you can overclock. I don't …

It's not just AMIKEY-2 that supports the PS/2 mouse. Just about every 8042 I've seen made after 1990 seems to support it.

The size of the cache gives absolutely no indication how much memory the board supports. That totally depends on what the chipset and BIOS can handle. The majority of 486 boards with 30-pin SIMM slots can accept up to 32MB using eight 4MB SIMMs. The ones that can take 16MB SIMMs are in the minority. …

The best part of this system is the keylock with the matching key. I guess those were still kind of around during the mid 90s, but rarely in OEM builds.

Normally I'm against using super fast CD-ROM drives in older systems because they have super ugly front bezels, but this one is great! It matches the grey floppy drives really well. What's the model number and where did you get it? The case has a nice bezel too. My friends father had one exactly …

In my experience it's pretty hard to get Cyrix 5x86 chips to POST at 5V. I have 5 or 6 of these chips, and I don't think any of them would do it. 150MHz on a Cyrix 5x86 is not realistic at any voltage with L1 cache enabled. 133MHz is pretty much the best you can ever hope for with this chip. On the …

I really hate the Trinity Works Power Stacker chips. At most, they needed 4 jumpers to setup the CPU, but instead they went with 14 tiny DIP switches that you can only access by removing the module from the CPU socket. To make matters even worse there were multiple versions of this thing and they …

8MB on a graphics card in 1996 wasn't totally unheard of, but not necessarily useful unless your card had a beefy RAMDAC and you had an expensive large CRT display to go with it. 4MB cards could do 1280x1024 in 16.7 million colours (packed pixel mode), which was beyond what most monitors back then …

There are no "period correct" CD-ROM drives for 286 systems...well, not mainstream ones at least. Whatever professionals were using at the time was almost certainly external SCSI, single speed and probably used caddies. Sometimes I will stick vintage drives that no longer work into my builds just …

They changed the media color on the newer faster blank cd's so only those rated at max of 8x or 16x will read properly on older 1x, 2x, 4x, 6x, etc drives.

For a '95 build I'd probably go with a 430FX motherboard with a COAST module even though they're less reliable, because it's the "wave of the future". The Trio64 is a good choice, but I think in 1995 everybody wanted a Matrox Millenium. SB16 was popular, but wavetable cards like the AWE32 were the …

Don't count on the clock doubling doing much of anything. Without cache, clock doubling doesn't seem very effective from what I've seen with TI486SXL CPUs. The more important features in this upgrade are improved memory management and 386 protected mode (if you have enough RAM).

SIPP *sockets* were very common on 286 boards, SIPP modules themselves not so much. Most 286 boards that could accept SIPP also accepted far more common DIP RAM. Almost every 1MB 286 I have seen used the DIP sockets and not SIPP.
