Wrote the program on a coding sheet (Z80 assembler), then hand-assembled into hex, and typed it in as such (I had built a simple terminal, and the Z80 was running under a little monitor program called MinMon that was a few hundred bytes long, that accepted the hex and stored it). Ah, those were the days! Tell that to the kids of today and they don't believe you...
