Sinclair ZX81 Computer Kits
February 8th, 2006
All parts are high quality and the glass epoxy PC board has a clearly silk screened parts legend. Further documentation can be found in the books section. Each kit contains all the necessary parts, including UK keyboard, case, printed circuit board, resistors, capacitors, connectors, integrated circuits, power supply (110v), cables etc. Assembly instructions are available in the Technical Support Section. 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.
Long live the ZX81!
Here’s the book that shows you how to use two fo the most powerful software packages for the Timex/Sinclair-VU-VALC and VU-VILE (The Organizer)! This conciese and crisply writeen guide offers practical “how-to” information to understanding and using these two multi-purpose program- unlike the briefly-documented reference manuals that accompany VU-CALC and VU-FILE.
This is the Spanish version of the ZX81 programming manual that Sinclair shipped with their kits and computers to South America. Over 200 pages.
Designed for use with the ZX81, TS1000, TS1500, or TS2068, the experiments in this book help develop programming and circuit building skills while illustrating important concepts in the physical sciences. Each experiment includes step-by-step directions, a list of necessary components, and easy-to-follow schematics and diagrams. These experiments show how microcomputers can be readily adapted for practical uses in the school, university, home or laboratory.
The INS and OUTS of the TS1000/ZX81 contains the complete circuit diagram of this amazing computer, as well as a full discussion of the unorthodox methods which are used in making this microcomputer do what it does. The author also includes a number of practical projects to enable you to take full advantage of the system’s hardware including expanding its memory capabilities. This INS and OUTS of the TS1000/ZX81 deals extensively with the hardware aspects of the TS1000/ZX81, and is a must for anyone interested in building their own peripherals for this computer.
This is an excellent way to introduce your family to BASIC on your Timex Sinclair 1500 and ZX-81 computer. You’ll find it filled with useful information — for managing household finances, using your Timex Sinclair as an electronic message board, using the computer as a calculator, solving complicated mathematical problems, and many other applications.
An excellent introduction to programming in BASIC on the Timex Sinclair 1500 and ZX-81. You’ll learn about programming techniques, see examples that show you how BASIC commands work, and find out how to write you own programs. This easy-to-read book takes you step-by-step through the BASIC programming language. You’ll be amazed at what you and your Sinclair computer can do!
