#5277 — nasm and z80

    Can nasm use the old Z80 procesor instruction set? I'm not sure how 
complicated it was but from what I've seen there are some strange opcodes or 
should I say, a strange instruction set to me. DAA is one instruction. It 
might be a little easier to grasp that before going to a limited set of 16 
bit assembly with nasm.

    If nasm will not work what can?

DAA is an instruction on 8080, Z-80 and x86, except in x86-64, where
it's been dropped (although it's still there when those processors are
executing other than 64-bit code).

NASM is x86 only, but there are a variety of Z-80 assemblers out
there.  You might start at:
