southern cross brief history

  • talking electronics TEC-1, 1983, i think it was influenced by kim-1 although the kim-1 was released by MOS the 6502 designers in 1976 as a way to get people using the 6502 processor. TEC-1 was designed specifically to get the ordinary bloke involved with computers.

  • Cris Jones
    I developed the Z80 Southern Cross Computer for Hong Kong based Kitsrus in 1992/93. The kit was based on the TEC-1 Computer that was designed by John Hardy and Ken Stone in 1983 and appeared in Australia's Talking Electronics Magazine Issue 10 March 1983.

  • Kitsrus distributed the kit into the US and the UK and was sold online from Hong Kong.

  • The Southern Cross Computer appeared in Australia's Silicon Chip Magazine in the August 1993 edition

my southern cross

  • i found this southern cross on ebay. its revision 3, and it came assembled.
  • description
    this is easier to program, still hand assembled machine code, but encourages building bit banged serial interface
    good documentation at the github page
    easy to interface too, plenty of projects out there
