Bought a good, functional (battery leakage present, will fix the issue by replacing the battery with a CR2032 (got the battery holder, as well as the board manual, BIOS, and battery replacement guide on vogonsdrivers.com prior to) Soyo SY-4SAW2 Rev WA3 motherboard.
Odd portion is the keyboard port. It's been replaced with a PS/2 keyboard connector, which is odd, yet satisfying, plus, it has a header for a PS/2 mouse, which is good (might look and see if that actually works).
Board works accordingly, just needs a new clock battery, slight trace patches, and that'll do.

Hardware, RAM, cache, and other info:
PS/2 keyboard connector, PS/2 mouse header (4x2), and NiCd battery (slight leakage):
Closeup of the battery and slight trace corrosion (will be easy to fix):
The board will be swapped with the PCChips M912 v1.7 board that is installed at the moment as well. I have a PCI video card, network card, 176MB worth (128MB (2x 64MB) EDO 60ns and 48MB (3x 16MB) FPM 70ns) of RAM, sound cards, VLB video card, Evergreen 586 (will set to Write-Back mode to test the turbo functionality to see if the board works with both WT and WB cache for turbo), and everything else that's already installed (FDDs, HDD, CD drives, keyboard, and mouse) will be used instead of swapping those around.
The board itself supports a PS/2 mouse, which is unusual for an AT 486 motherboard to support it, but it's pretty cool.
Has the following:
4x PCI slots
4x ISA slots + 1 VLB slot
512KB L2 cache installed (maximum supported, sadly, but will do)
PS/2 keyboard connector in place of the AT keyboard connector, which is also interesting to see on a motherboard
PS/2 mouse header on the motherboard (will test that out with a PS/2 mouse connector header I have in my Socket 7 system)
Integrated I/O (FDD, Primary IDE, Secondary IDE, Parallel, and Serial port headers)
Leaking NiCd battery that'll be removed and a CR2032 battery will be installed for the CMOS settings and D2 will be removed to prevent the charging circuit from being used
The board itself is in working order and will be getting the treatment to make it more appealing.
This'll be mostly for benchmarkings and game playing, including running Windows 95.
The pictures above are the seller's photos in case you're wondering. Once I receive the board, I'll be doing the battery swap, trace inspection, cleaning, and repairs (to be safe), then post pictures of the board itself, and last but not least, backing up the BIOS and making another BIOS chip as a spare in case the one in the system stops working one day.
