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.
Doug.
