Z80 Southern Cross SBC Rev. 3.2 - PCB

Autor: Craig RS Jones
Projektbeschreibung: https://github.com/crsjones/Southern-Cross-Computer-z80

Craig 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. A follow up article appeared in Silicon Chip in December 1993 describing the 8x8 LED Matrix and 8 Channel Relay add-on board.

A facebook group for the Southern Cross has been established [https://www.facebook.com/groups/1553416258519631).

The motherboard SC126 provides a Z180 CPU (18MHz) with 512K Flash-ROM, 512K RAM, 2 x serial ports and SPI /SD-Card, RESET generator and a real-time clock on one board, as well as an expansion possibility via backplanes.

While a functional Z80 system in the minimum configuration consists of SC108 CPU, a SIO (e.g. SC110, or SC132) and a backplane (e.g. SC112), the motherboard SC126 offers all this - and even more on one board for the Z180. SC130 can be extended via additional backplanes.

IMPORTANT: The picture of the assembled board is only for illustration. The offer includes NO components - only the board.
