Am386 DX-40 Brief Video Playback Demonstration
That's right, I'm building a late-era 386 system! It still needs more upgrades, but so far it's already quite competent for a number of things.

Most notably, the Tseng Labs ET4000 supplies some impressive video bandwidth along with support for a variety of resolutions, color depths, and refresh rates. The variant I'm using does not have hardware GUI acceleration, and even then it appears to handle itself very well with a 16-bit color depth being used.

The small 40MHz 386DX CPU is factory soldered onto a Biostar MB-1333/40UCQ-B motherboard, which is perhaps the smallest retro board I own, close to the dimensions of the Mini ITX form factor. While the Am386 DX-40 is the fastest 386 ever released to the market, it wouldn't reach anywhere near the performance demonstrated in this video without the 128KB of onboard cache memory installed here. This abundance of cache could warrant installing 16MB of RAM in place of the 4MB used here; that along with a coprocessor are the only upgrades I'd really need to make at this point.

I know a 386 would be better suited to Windows 3.1x, but I wanted to see how Windows 95 would run on here, anyway. Apart from regular virtual memory swapping, it's very much usable on here, so I'm pretty confident I can also run MS-DOS 6.22 without running into any OS-related bottlenecks; I've been told about how MS-DOS 5.0 is better for most 386 and earlier systems because its programs don't take up as much conventional memory, if I recall correctly.

Of course, when it comes to running Windows 95 on a 386SX... well, that's something I'm unable to describe at this time.
