Huh? I count at least for 32bit wide becasue this machine seems to
do 32bits thing and each VRAM chip is 256K x 8bit dual port. 8 chips
total feeding the BT458LPJ125 ramdac.

Oh that! It matches!

That one? Well, I could send out whole board as a spare part
with that video daughter board. Bit battered looking, I afraid.
Want to trade? I'm looking in area of peecee parts.

No, I have to make do with custom PSU adapter plugs when I do have
info.

Emanuel did said about standard parity simms in those boards, I
thought so because of that diagnostic LEDs when I tried my simms in
it.

The story I got those 3 boards was a guy offered me those boards and
he wants to keep those boxes. I know it's dumb and that was over 4
years ago.

Okay I will try again.
