The Sinclair ZX81 was released by Sinclair Research as the follow-up to the successful ZX80. It shared its predecessors characteristics of a Z80 CPU, membrane keyboard, 1K RAM, black and white display and lack of sound. The ROM, however, was doubled to 8K and the machine ran faster. Like the ZX80, it was available for purchase ready-made or in kit form. The model shown here has Sinclair's infamous 16K ram pack; notoriously prone to wobbling when keys were pressed, with the potential to crash the machine and lose all the data.

Although it retained the Sinclair name, the Spectrum +2 was a product from the Amstrad stable, following their purchase of Sinclair in 1986. As such, it is no coincidence that the design bears more than a passing resemblance to Amstrad's own CPC 464 system. A later variant, the Spectrum +3, con... (read more)Sinclair, 1986
An update to the Spectrum that essentially took the 48K model and added a QL-style keyboard, enabling the Spectrum to at least in part escape the criticism that was often leveled at the 'dead flesh' feel of the rubber-keyed version (although in actual fact the feel of the keyboard was still very ...
