TV80 Miles Gordon Technology SAM Coupé ZX Spectrum Amstrad Sinclair QL
The combination of the market failure of the Sinclair QL and a portable TV product called the TV80 led Sinclair Research into financial difficulties in 1985. A year later Sinclair sold the rights to the computer products to Amstrad. Four further models in the Spectrum range would be released by Amstrad using the Sinclair brand name. The ZX Spectrum +2 included an integrated tape recorder and the +3 model incorporated a 3-inch CF2 disk drive. Production continued under Amstrad until 1992. Miles Gordon Technology attempted to release a successor to the Spectrum known as the SAM Coupé in 1989, but this was not a commercial success.
