Bought and received this board a few days ago, forgot to post about it. It's an Austin Computer Systems 33VL 386DX board, that I got for €25. Very good price, but it does have some work cut out for me. It's clearly been stored in a box full of other things or something like that, given it's fairly dinged up. Some of the SIMM slots have bent pins, but seemingly not bad enough to short or not make contact at all. One SIMM slot is really shot, and probably needs replacing. One ISA slot's a bit bent, and another few have pins that are slightly pushed back, but that probably can be massaged back into place. The board has a chipped off corner, and some top layer chipping next to the ISA slots, but both of these spots don't have traces or components on them, so it's not too bad. I might get some UV soldermask to cover it up, to prevent further chipping.
The Dallas RTC (very Texan thing going on here) has already been desoldered and I already have an idea how to mount the CR2032 to it, which I'll post later. The chipset QFP pins are all fine, and despite some scuffing and scratching, no traces appear to be damaged. Could be much, much worse, this board has had some luck getting damaged where it doesn't matter too much, or can be relatively easily fixed. Online resources say this board will work with 33MHz and 40MHz 386DX chips, so an Am386DX40 is on my way from China. Just need to find a good VGA card, sound card, NIC, a good amount of memory, and maybe a 387 to go with it, to build a nice 386 rig.
There were two nice AT systems with good early 90s cases for such a build at my internship, but sadly I won't be going there for a while due to the COVID-19 situation. Hopefully those will still be there, and I'll be allowed to take those away, as they're in the storage room with a pile of other systems that were taken from clients when the company upgraded their systems. One is still its original color, the other one's been painted black. I did do a quick test of the black one, and that had a Pentium Socket 7 system of some kind. I do hope my boss won't do a clean up of those while I'm gone!
