Bill Garber would be good one to talk to about this. He is in the hospital at the moment, though. He may answer in this post when he returns. Dan Foster wrote:
What's the speed? 120ns? 150ns? I know the DRAM was 120ns but less sure about the ROM. Would a 27C010 do? (Assuming one had a 32-to-28-pin socket adapter, especially if on a ROM 01 system.) On a different tangent -- this time, RAM-related: Is banks $80 through $EF (ROM 01) or $80-$DF + $E2-$EF (ROM 03) controlled by the FPI as fast RAM? Or does memory accesses to these banks slow down to the slow RAM access? -Dan
