Actually, I'll grant it's not microcode per se, but it's a table-driven
system with a multiple-cycle-per-instruction clock that steps thru the
table, so now it's an argument more over "what is microcode" than it is over
whether a 6502 has microcode.
I'd say anything that steps thru a ROM with a counter during one instruction
is probably microcode, myself.

that the code does what you think it does, even if
it doesn't do what you wanted.
