Sinclair Radionics, Links to other www sites
Sinclair Story. This is a scan of the book by Rodney Dale which was written with Clive Sinclair's approval - it is the source of much of the information (and much of the fiction!) on the pages below.
Planet Sinclair. The most comprehensive archive of data on the subject. It is mainly correct - but there are some errors. The site's domain (http://ntnu.no/) is owned by the Norwegian University of Science and Technology (NTNU). Planet Sinclair is part of the students web site.
Kio's archive has lots of interesting information mostly on early computers. Sinclair ZX Computers Archive has much more than computers. His Other Inventions area has interesting data on many other Sinclair products - not just Sinclair Radionics.
Sinclair Research but has a section on the first 20 years, 1961 to 1980.
