I always thought that the Zilog mnemonics were better than Intel's. I learned Intel first, but immediately recognized that Zilog's were better once I became aware of them.

The only C compiler I had on CP/M was BDS C. It was fairly limited and had no floating point support whatsoever. Maybe that's the one you're thinking of?

This one was called Aztec and Manx C, depending on what part you looked at. It lacked bit field struct members and I think a couple of other features but don't remember now.

I learned Zilog first and agree with you. I had to keep an 8080 manual handy for a while to make any sense out of that compiler output.

Good(?) times.

I used Aztec C for the 68k on some embedded projects for work in the late 80's. The 68k version was a full-featured C implementation complete with IEEE-754 floating-point math and bit fields. I liked the fact that Aztec included the source code for parts of their libraries so one could write their own drivers for stdio devices. I still have that code somewhere...
