Excellent, thanks ... I'll see what I can do about the Rainbow.
I'm just digging out information at the moment: The thing about the two DMV hex images was, that one machine would accept my 68k module, the other not. This is why I dumped their respective ROMS (so they're both main ROMs from the Z80 mainboard)... I now found out that it's not the ROM after all, but the type of internal 8086 adapter used. The one that accepts the third (68k) coprocessor has interrupts enabled ... I'll try to dump its proms' content tonight.
It would be very helpful if you could tell me what specific information or code is needed next.
Thanks for all the efforts, this is a dream coming true.
Robert
