Well, I count 20 bytes worth of program, so 100 clock cycles is not
totally out of the question if each byte takes at least one cycle to
fetch (should be true), and a couple of cycles to execute (shouldn't be
true - instruction timings are supposed to be for the whole
instruction, I think)   It's about what i'd expect from an old z80 with
4-cycle fetches; your chip doesn't have an "old z80 compatible slow
mode" that you got into somehow, does it?
