One equipped with:

  • NOVA 3 CPU, PWRFAIL, PRLOAD, 256KW
  • NOVA 3 TRIPPLE OPT, MMPU, PAR, MUL/DIV, RTC
  • 64KW Plessey, 128K SC, W PAR, 0-127
  • DGC NOVA CASSETTE I/O, $TTI/O, 9600 B, RTC
  • DISK CARTRIDGE CONTROL DGC NOVA, DKP, 4234, 6030
  • DGC NOVA CASSETTE I/O, $TTI/O, 9600 B, RTC

The other is an empty chassis, both with faulty power supplies. I contacted Bruce Ray of Wild Hare Computer Systems and Bruce provided me with Nova 3/12 Power Supply and backplane drawings. I still have to troubleshoot and repair the power supplies, but at least I now have the drawings and the tools.
