Although this video involves many companies such as Sinclair Radionics, Sinclair Instrument Ltd, Thandar Ltd and Cambridge Processor Unit, it boils down to the trading names of Acorn Computers and Sinclair Research Ltd and the rivalry between them during the early 1980s era of home computers. Each company respectively owned by Chris Curry (and Herman Hauser) and Clive Sinclair. This video charts the whole story from the inception of Clive Sinclair’s first company, Sinclair Radionics, to when Chris Curry started working for him, to when he left and formed Acorn and when the rivalry of early ’80s micros set in with each company trying to compete against other in gaming, educational and professional markets.
