Is it really? Do
mov a,m
or
dad d
exist on X86? I always got the impression that there wasn't real
compatibility between the 8080 and 8086, just that they made the
instruction sets similar enough that translating your code wasn't
*that* painful?
Euch. I really hate Intel opcodes. I much preferred Zilog's Z80
mnemonics for the same operations which, if I remember correctly, were
LD A,(HL) and ADD HL,DE for the above two instructions, respectively.
