I dont even want the c64 to GET the nmi. Perhaps a latch that can be set to mask it? The idea isnt to block the NMI (is there a separate nmi line? I didnt notice), but to block the parity error signal. > > > Since the c64 wont be generating parity (anyone got a > > parity gen circuit?), > > Here you got me confused.

The idea is to put the c64 on an empty isa bus as the primary isa bus controller. - This message was sent through the cbm-hackers mailing list.
