The Sinclair QL was Sir Clive Sinclair's attempt at a computer for business. It was released in January 1984, a few days before the Apple [[Macintosh]] and a few months before the Amstrad CPC 464.
The QL signalled a move away from Sinclair's "traditional" use of the [[Z80 ]] processor to a multi-tasking system based on a 68008 processor and 8049 second processor.
The QL features a structured on-board version of BASIC called SuperBASIC, and a multi-tasking operating system (QDOS), which was quite an innovation back in its launch days!
150,000 units were sold. It was Immediately after acquiring Sinclair, Amstrad discontinued the QL in April 1986.
