The system used a passive Bus architecture with no motherboard - all electronics were contained on a number of cards interconnected by ribbon cable. The only Processor offered was a Z80 (hence the name), with up to 256K of RAM . Outputs to an external video monitor and / or TV set were provided for the display. Mass Storage was either via Cassette Tape , or Floppy Disk (which required a Disk Controller card). The basic system came with a basic monochrome Graphics Card , which could be enhanced with a hi-res board. The Keyboard was separate and came in a tough metal case. Early versions were contained in a light blue metal case with a white front and only had a cassette interface. Only a small number of these were made. Later versions came in a black metal case and typically contained two 5.25" floppy drives, although the cassette interface was also retained. The machine came with a monitor program in ROM , so BASIC or other languages had to be loaded on start-up. For disc-based models, the CP/M operating system was first loaded. The 380Z was sold mainly to schools in the UK , and some were also sold to industry. EXTERNAL LINKS |
