    I've seen a few loose ones go on eBay for $200. $300 is sadly a fair price for a NIB example.

    The only way you're going to get one for cheap is if the seller doesn't know what they have. I picked...

    I'd say definitely worth looking into, and always worth the effort!

    I think the sales brochure for the Toshiba T1200 laptop mentions a socket for an 80C87 math coprocessor. No idea if it was just a typo, or perhaps a socket for a product that never materialized.

    Really? Can you give me an example of such a board?

    As far as I have seen, 8087s from Cyrix and AMD basically do not exist. I think both of these companies and NEC attempted to clone one, but were...

    I am pretty sure the first 486s were the DX 25 and 33. Wikipedia reports a 20MHz version, but I think it might be an error. Anyone have proof?

    As far as I know, the 16 and 20MHz parts were only...

    I can't speak for all SB16s, but my 2230 line out had a fairly audible hum. Not good.

    Looks like a really nice one. Good motherboard, and an SB 2.0. Probably 8MB.

    I'd keep the 5.25" drive. CD-ROM drives were pretty uncommon on 386s. IF you want one, use a back pack drive, or a SCSI...

    For a 486 I think an SB16 is a good choice, but I recommend using computer speakers and not hooking up to an amp, as they don't produce clean sound. The 17xx or 22xx series are probably the ones to...

    I think they were just being lazy. This company also made 286 to 486 upgrade modules that used the same chip. They probably shared advertising material for these two products and forgot to remove...

    I don't know, I think they are kind of notorious for partially working.

    There are compatibility issues with FPUs, and sometimes they won't double. Sometimes the cache doesn't get along with...

    I was always kind of curious why an 80288 never existed. Every other CPU seemed to have a cut down version except the 286. Even the 80186 got an 80188.

    The second board for sale is almost certainly "mini EISA", and there is a small chance that the VLB slot could be proprietary local bus (apparently some used the same connectors and placement as VLB)...

    According to that wikichip, the non-enhanced versions of DX4 should be .5 micron, which sounds about right to me. However, I don't know how much faith I'd put into the wikichip, because it lists...

    I think I heard a rumour that the AMD DX4s with 16kb were really just rebadged DX5s. As far as I know, they're all 4X multiplier capable. In any case, these didn't show up until the 486 was horribly...

    Please back up the claim that there was a 5V .7 micron DX4 from AMD. I have never seen or heard of such a thing. I suspect if it exists, it's only an ES. I know for a fact that the latest models were...

    We were discussing these TI chips in another thread. They are called TI486SXLC or SXLC2. They are both capable of clock doubling despite the different labels.

    There are actually three different...

    These chips are Cyrix based, but apparently TI made unauthorised modifications, mainly increasing the cache size from 1kb to 8kb, and repurposing one of the CPU cache registers to enable/disable the...

    Your reply is well informed, but not correct. Time to read up on TI "potomac" CPUs.

    TI486SXL(C) CPUs are somewhat notorious for not being able to double. I think it has something to do with the way TI implements the doubling feature, which unlike most other CPUs is disabled by...

    If your 486 already has built in local bus graphics, I doubt any ISA replacement would be worthwhile. W32P is already a pretty decent solution for local bus.

    S3 968 and GD5446 should both offer...

    Ah, I thought we were talking about ISA cards.
    If you're wanting PCI, it's a totally different game. Just get a Trio64V+ and be done with it.

    S3 928 is probably a poor choice for PCI...I don't...

    Windows accellerators only really "sucked" at VGA graphics in the 1990-1992 period. After that the situation improved substantially. Pretty much all the S3 VRAM based cards from the 928 onward had...

    Some of the 3rd party socket4 upgrades were more interesting (and probably even rarer). Do a search for Powerleap PL-54C/MMX

    Here are the dumps. Neither the board nor the chips specified which was even or which was odd, so I just named them randomly. If one combination doesn't work, try swapping them around.
