Hallo Gerrit, > Your cartridge does not use the R/_W signal though, ...

Just create an OR gate of those two NOR gates and use it to combine R/_W with IO1. But I could think of a practical reason not to do that: it would be much more complicated to design the PCB. Just my two cents... -- Kind regards / Met vriendelijke groet, Ruud Baltissen www.Baltissen.org Message was sent through the cbm-hackers mailing listReceived on 2013-06-18 20:00:30
