I also had some ideas yesterday when I was participating in the newsgroup
comp.sys.sinclair (yes, I read and post there as well as in comp.*.cbm).
The C compiler environment Z88DK for the Z80 was discussed, and it was
mentioned it even had some support for the "Commode 128" as the Speccy
people tend to call our beloved Commodores.
This had me thinking: if CC65 etc supports the C128 in 8502 mode and
Z88DK supports it in Z80 mode, would it be possible to link those two
together into one C compiler which could optimize and do neccessary
processor switching automatically?
Not that it would analyse a whole program and generate code for one of the
two, but whenever possible decide this subroutine is better suited in Z80
than 6502 and vice versa. I have absolutely no idea how hard it would be
to link together the two compilers in the first place, and the optimizing
would probably be even harder to do, but it might be really cool.
What other retro computers were there with two different CPUs which could
be activated during the program? Another other 6502 + Z80 setup?
