This brought back my collage days! I had job coding Z80 ASM to control electronics and RS232 data links... such fun :) People would give you such funny looks when they saw you staring into a terminal of hex and you pointing out .. ahh that 3E CF needs to be 3E D3 :) Best thing is that I ending up knowing all the op-codes and most of the instruction timings of by heart (which made interfacing to those 16 x 2 line LCD modules easier) NMI anyone?
