I seem to be on a roll recently. Managed to get all this from two generous locals today.
ATI Rage II +DVD - Some bent pins on the main chip. When I tried to bend them back, one of them came clean off. Don't think I'll be saving it.
ATI Radeon 32M
ATI Rage 128
NVidia FX 5200
NVidia Geforce 3 Ti 200 - No bracket. Not sure what to do about that yet.
NVidia TNT 2 Ultra - Bent the bracket back in shape. The fan was barely working, so I attached a heatsink with a adhesive thermal pad and screwed a small fan into it. I'd like to find a heatsink solution that uses the mounting holes, but I'm not sure if that's something that would be readily available.
Avance Logic ALS4000
Aureal Vortex AU8820
BTC 1817D OPTi 92C931
SB 16 CT4180
SB AWE 64 CT4380
SB Pro 2 CT1600 - Two of them! On the same day! How does that even happen?
Panasonic floppy drive
32MB of RAM
200MHz Pentium MMX
Gigabyte GA-586HX rev 1.55 - Managed to find a patched BIOS to fix the large HDD bug, but it wasn't straight forward. Needed to use archive.org on a dead link to find a copy of it. Now, other than the dead battery, it seems to be working great.
So the Rage II+DVD seems to be the only dud, and I'm not gonna lose sleep over that. I haven't had time to really put everything through its paces, but all the sound cards output music and sound effects, and all the video cards are showing a clean image. And the few I've tested in 3D have been good there too.
Phew, what a day!
