C compilers for 8 bit machines

[Mark Horton]

I would appreciate any references to C compilers for popular 8 bit
machines, such as the Apple II, Commodore 64, Atari 800, and CP/M machines.
I'd prefer products, but public domain offerings are OK too, especially
if a source can be given.

This info is for a book about C portability, so you probably don't want
to offer to send a copy of Tiny C personally.  Also, any comments about
the compiler you mention (if you like it, what it's limits are, etc)
would be appreciated.

Thanks in advance,
