The Sinclair QL is a computer developed in 1983 by Sinclair Research. It was based around a 68008 processor and initially shipped with 128Kb of RAM and two 100Kb microdrive units for storage.
Psion supplied a suite of applications including a word processor, spreadsheet, database and charting package with the machine.
The machine was originally intended to use a Z80 processor like its predecessors.
The operating system was written mostly by Tony Tebby.
