I dug up that 486 motherboard I mentioned yesterday and here are
the specs:

6.75" x 8.5" (1/2 usual "baby-AT" size)
Cyrix CX486DLC 40mhz
ULSI Math*Co DX (40mhz?)
AMI BIOS
256K cache
8 30pin SIMM sockets (sorry don't have any SIMMs for it)
5 16bit ISA slots
1  8bit ISA slot

The Cyrix was a drop-in replacement for the 386 with the same pinout,
so I suspect the motherboard is really a 386 design.  I powered the
board up with some borrowed SIMMs and graphics card and it made the
expected clicking sounds as counted it memory and it displayed the
bios info on the screen.  Beyond that I don't know how well it works.

The "manual" is two pages of jumper settings and a SIMM map. The
board can take 256k, 1M, and 4M 30pin SIMMs (max 32M).

Since Roger's board has memory on it, that might be better.  And
seeing as how this is a fairly large platform, I don't think
the small size of my board will be much of an advantage.  I
guess the wheelchair sub-committee :-) should plan this out and
let us know which parts they want...
