It was commissioned by Sinclair Research in February 1983. However, after the official launch of the QL in January 1984, 68K/OS was rejected, and production QLs shipped with Sinclair's own Qdos operating system.[1]

GST later released 68K/OS as an alternative to Qdos, in the form of an EPROM expansion card,[2] and also planned to use it on single-board computers based on the QL's hardware.[1]

The operating system was developed by Chris Scheybeler,[3] Tim Ward,[2] Howard Chalkley and others.

The few ROM cards that were made mean that surviving examples now fetch a high price: On Feb 04, 2010 one sold for £310 on eBay.[4]
