As another example of what Carte Blanche is good for Steve made a configuration that emulates (mimics?) the Stellation Mill 6809 card. It needs some testing and polishing. I only have one disk image 6809asm.dsk that has an inconclusive demo. With no 6809 card at all it doesn't say "card not found" or whatever. The only difference I observe with the card is that the 6502 program runs slower because 6809 uses a lot of bus cycles.
Alex,It would be great to include the logic on that little piggyback card so OS-9 will run. Someone (forgot who, sorry) mentioned that it remapped the apple in the same manner as a Z80 Softcard.
