Agree, but it might be worth the effort to have a look at emulation the interrupt logic too, if it's not too much trouble. Afaik the interrupt logic is only used in one place in the CBM-II series and nowhere else, so if we are short on cells in some kind of programmable logic it might be okay to just emulate enough to make the CBM-II work with the existing kernal, if that even can save something. (It would probably be a saving to hard code the replacements as 6523's or 6525 with interrupt controller always enabled). -- (\_/) Copy the bunny to your mails to help (O.o) him achieve world domination.
