That's the way we used to program Z80s - when the poor 4MHz chip was made to work for its living. Counting clock cycles per instruction? Of course, that way you could get it to work harder & faster, and when you have only 8k of ROM, making every instruction relevant really matters.
RPi Zero is probably the way to go with your cassette recorder but I never found out how to program those in machine code, and I never really learnt any sort of higher level language....
