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?
