It was a self-designed wire wrapped 8068 with 20k of RAM and a 2k EEPROM into which fit a bootstrapped operating system I wrote in assembler. Its one program (to generate front and rear "gates" to track a simulated radar pulse) was loaded via an ordinary tape recorder via a simple ADC and controller (also self-authored).
