I've done it with C77 as master and 74A as slave
in the production version, but have run the master
code on the 74A as a testbed when we ran out
77s back in the spring, and couldn't source
any (remember that fiasco ? Nobody could get
a 77 to save their grandmother's life for about
6 weeks back in March/April sometime).

Anyway, the code is in production, so it works.
The gotcha is that it's for C (Hi-Tech flavour).
The upside is that, except for the actual bit
bashing that shoves the 1's & 0's out the door,
the rest is pretty much 1-for-1 mappable to
assembly code. Except for the bank switching,
too, of course 8^)

If you are still interested, even though its in
C, let me know.
