Got lucky at the flea market this past couple of months so I tought I'd share some of my findings.
386 motherboard with L2 cache and an AMD 386-DX40 sitting on some kind of interposer - untested, but looks like it's all there, and I can't see any corrosion. No barrel battery witch is a plus, but on the other hand it's using a Dallas RTC witch I am not fond of.
These 3 are all VIA 82C694T Pentium III Tualatin motherboards with an ISA slot. I've been hunting boards like these for hybrid DOS/Win9x builds. All of them tested fine, but they all had bad caps. The Epox and MSI got fresh 1500uf 6.3v caps. Both had 3-4 bloated capacitors, all 1500uf, but I replaced all 1500uf caps on these boards just to be safe. The Trancend on the other hand has loads of bloted caps, over 6 1000uf and 3 or 4 1500uf caps. It posts, but I won't do any extensive testing on her until I can order new capacitors. The MSI has pretty decent overclocking options, I was able to run one of my 1200MHz Celeron Tualatin chips at 1600MHz (12x133 / 1.6v) stable. The Epox was a really nice surprise since it FULLY supports the VIA C3 Nemiah. I even got new bios options when running the C3, like "C3 Multiplier Selection". The MSI and Trancend motherboards did not come with a northbridge heatsink, witch is odd since the 694T gets pretty hot when running a Pentium 3-S (measured 67C with an IR thermometer) - so I added a heatsink on the MSI and plan to add one to the Trancend after recapping.
A couple of creative sound cards (SB16 and an AWE64 value), a couple of ESS sound cards and a Radeon 8500 AIW.
