My first Z-80 was the Timex-Sinclair 1000 with 16 Kb ram and integrated basic. My second was a computer I made up of parts (TTL chips) and an 80 Amp 8V DC power supply. 8 Z-80s at 8 MHz with an interleaved 8-phase clock at 64 MB and 64 KB shared memory. 'console' was a hex keypad and hex LED displays. Programming was via machine code. Couldn't afford mass storage so I left it on. Now those were the days. I built it when I was a teenager after reading "2001 A Space Odessey" for the first time and wanted to learn how orbital mechanics worked: I needed a better calculator. It would do 128-bit integer math. I never needed to calculate a transfer obit to jupiter in real life but I leared a lot about math and electronics.
