At this point, the ACA500plus (which is async, so loses a cycle here and there) beats your sync design just because of MapROM at 14MHz. You can beat the ACA500plus at 14MHz if you implement MapROM. However, you won't reach the ACA500plus speed if it's clocked at 21MHz or more :-)

Thanks for the advice.
