Up for auction on ebay UK is this very interesting collection of rare Sinclair prototypes which were given to the seller’s father in an office clear out by Sir Clive himself. These prototypes are all non-working design-stage models of the ZX80, ZX81 and Spectrum plus some models of unreleased computers. These prototypes shed some light on the design process at Sinclair Research back in the 80s.
I don’t have to tell Sinclair collectors how exciting these protos are. Probably a once in a lifetime chance of adding a unique and personal piece of Sinclair history to your collection. Only one day left at time of writing so get your skates on!
