Sinclair QL

Launch 1984
Launch 1986

“The QL (“Quantum Leap”) was Sinclair’s attempt at a business computer. Not only was it incompatible with its popular sibling, the ZX Spectrum, it used a proprietary media format: The Microdrive.

The QL was unable to compete with Macintosh and IBM computers in the business space and was discontinued when Amstrad acquired Sinclair’s computer products in 1986.
