maybe this is usefull for plasmab and his cd32.
You can get the 2MB ROM chips in 100ns or 50ns versions.

50ns is quicker than "FAST RAM" as most CPU cards that use 80ns down to 60ns RAM?

Or is there something else in the A4000 limiting ROM access to slower speeds?
I know there is a jumper on the motherboard for ROM speed. But can that be bypassed all together and force them to runt 50ns?
