I got quite a few things in the mail today.. I'll list them from boring to exciting:

A S3 Trio3D/2X as a possible primary card for mySuper Socket7 Voodoo 2 SLI build.

An ATI Rage 128 Pro as a possible primary card for mySuper Socket7 Voodoo 2 SLI build.

A Cirrus Logic CL-GD5401 (Acumos AVGA01) ISA VGA

A Biostar MB-8433UUD-A VER:2 Socket 3 motherboard (As far as I can tell it is one of the better 486 PCI motherboards out there, but the Dallas RTC is dead and soldered on 🙁 I'll need to replace it with a socket, and later a working Dallas RTC (or mod this one for an external coin cell..))
The strange thing about this motherboard is, it came with 1 16MB and 4 4MB SIMMs, and it POSTs with 28MB memory. I never thought these kinds of motherboards accepted mismatched RAM in the same bank?

And the star of the show, an IBM 5x86C 100MHz. This is the reason I bought the above motherboard - there was a POST screenshot on the listing that said Cyrix 5x86 100MHz so I immediately grabbed it for $20. It works, but has a weird twist:

The pins are either corroded (never saw this happen before) or covered with a strange black substance.. Brushing the pins under running water got rid of some of it but not these that remain. Not sure how to tackle cleaning this, or whether I should even attempt..
