Sigh, I could live with 1 MBit of display memory for B/W.

SMC FDC37c663 - has 16550's, IDE.

Is this "20 MHz bus/ 40 MHz internal"?

8 MBytes on board sounds reasonable.

8742 with some kind of BIOS. Of course, we won't be using the "gatea20"

That's always my problem. Like the fact that I should be home by now.
