Hi maybe the false NMI info originated from me. Few years ago I read a CP/M cartridge review, and maybe misunderstood something. The fact is (as gerliczer highlighted correctly) that NMI lines are not connected at all on the C64 CP/M schematics. Maybe just because noone developped an external CPU for plus/4 it does not mean it is impossible.
