When completed, the ZX81
computer can hook up to Channel 33 on any black & white or color TV for
its video display (UK (PAL) and US (NTSC) Compatible - selectable by jumper when the kit is
being assembled). It has a complete (English) BASIC language
interpreter in ROM memory, and it can save and load progams on standard cassette
tape recorders. The kit's five Integrated
Circuits make clear the architecture of a typical computer. Processor (1) , ROM
(1), RAM (2) , and Glue Logic (1).
As the kits were originally intended for the South American market, we currently have no
UK/European power supplies or manuals available. Generic 9v 0.7A power supplys are available are
available cheaply from retailers such as Tandy or Maplin. Searching the internet often
turns up such items at surplus electrical disposal stores.
