It was 40 years ago now and my memory isn't what it was, but we would use machine code rather than assembler on the Z-80 because we could always use less memory and because we could select op codes that used fewer clock cycles, both of which were important considerations. Possibly the assembler available to us at the time didn't allow us to do one or both of these things. I don't remember any irritation about programming in machine code, my feeling now is that we had some satisfaction in making code as efficient as possible

I still have my Rodney Zaks book on the shelf!
