Sinclair QDOS

QDOS (sometimes written as Qdos in official literature; the name is not regarded as an acronym; also see the identically-pronounced word kudos) is the multitasking operating system found on the Sinclair QL personal computer and its clones. It was designed by Tony Tebby whilst working at Sinclair Research, as an in-house alternative to 68K/OS, which was later cancelled by Sinclair, but released by original authors GST Computer Systems.
