My followup on the Z-80 card is a follows: 1) I was told that the on board ram on the apple was too slow for the z80 running at 6MHZ. 2) If the 6MHZ z80 has it's own ram then this problem is solved!! 3) If they only sell the 6MHZ cards with their own ram Then obviously it's not your problem. 4) I have not had a chance to actually check the speed of the on board rams so They may run at 6MHZ ??
