QL (Quantum Leap)

The Sinclair QL was the first attempt for Clive Sinclair to produce a computer for business. But after the success of the ZX-81 and ZX Spectrum, the QL can also be regarded as the first failure of Sinclair. In January 1984, Clive Sinclair presents the QL to the press, unveiling a very promising and inventive machine, based on the 68008 processor from Motorola. Indeed it was the first home computer based on a 32 bits CPU, just a few days before the Apple Macintosh. It was important for Clive Sinclair to unveil the QL before the Macintosh, but that was also one of the main reasons for the QL's failure...

The British ICL company conceived a desktop information system based on the QL mainboard. It was sold in the U.K. under the names One Per Desk and Merlin Tonto. The same model was also sold in Australia, with the name Telecom Computerphone.
