Hit a yard sale today with a LOT of motherboards and ISA cards.
Unfortunately the entire box of ISA cards was ruined by nesting rats. Their urine had corroded virtually every card to one degree or another, including a few STB Ultrasound clones and about 20 SB/SBPro/SB16 cards!!!
I did pull a few interesting cards out that seemed only a little urine-damaged: An Intergraph Intense 3d and some sort of weird "SBAWE32UPG" card, which is an EMU-8000 card with two 30 pin SIMM sockets? Never see one of those before. Add-on for SB16 users, maybe? UNFORTUNATELY the Intergraph has two missing leads on one of the 3DFX chips, so I doubt it is functional at all. 🙁
I also grabbed a bunch of Intel NICs that are only "lightly peed on", and a few miscellaneous floppy controllers and multi IO cards that were all still clean.
There was a Trident ISA card with interesting looking memory package:
The motherboards were in excellent condition, and I picked up a nice looking Pentium Pro board (not sure which processor it is) and another half-dozen miscellaneous socket 370 and socket 7 systems with processors, and two slot 1 processors and two what I presume are "slotket" adapters I've read about here.
All told, cost me $20, so I am pretty pleased.
