Each kit contains all the necessary parts, including keyboard, case, printed circuit board, resistors, capacitors, connectors, integrated circuits, power supply, cables etc. When completed the computer can be used on UHF Channel 33 of any Black & White or Color TV. It is possible to use the computer on UK (50 hertz) and US (60 hertz) televisions by setting a 'jumper' on the circuit board.
The kits do not include a manual, so have a look at Books before you order.
Our Yahoo group has an online version
of the instructions
in html format and scans of the original assembly instructions
(print these off before you build!)
It also provides circuit diagrams and useful ZX links.
