Cambridge Systems Technology (CST) was a company formed in the early 1980s by ex-Torch Computers engineers David Oliver and Martin Baines, to produce peripherals for the BBC Micro, and later, with Graham Priestley, Sinclair QL microcomputers.{{Cite news |date=January 1984 |title=News |volume=1 |work=The Micro User |issue=11 |url=http://myweb.tiscali.co.uk/themicrouser/news/01-11.htm |access-date=5 April 2023 |archive-date=23 July 2018 |archive-url=https://web.archive.org/web/20180723095732/http://myweb.tiscali.co.uk/themicrouser/news/01-11.htm |url-status=bot: unknown }}{{Cite web |last=Graham |first=Adrian |title=Binary Dinosaurs - Cambridge Systems Technology |url=https://www.binarydinosaurs.co.uk/Museum/cst/index.php |access-date=2023-04-05 |website=www.binarydinosaurs.co.uk}} Products included IEEE 488, floppy disk and SCSI interfaces.{{Cite web |title=Cambridge Systems Technology Floppy Disk Interface - Peripheral - Computing History |url=https://www.computinghistory.org.uk/det/55407/Cambridge-Systems-Technology-Floppy-Disk-Interface/ |access-date=2023-04-05 |website=www.computinghistory.org.uk}} File:Sinclair QL, 512 K Expanderam and CST QDisc.jpg for Sinclair QL]]

Following the demise of the Sinclair QL in 1986, CST began producing the Thor series of QL-compatible personal computers. These had limited commercial success, and CST had ceased trading by the end of the decade.
