(replace -at- with @) - The semi-official website related to the Sinclair QL Professional Computer. Sinclair QL Software download and more. Come and get THE DISTRIBUTION with 4 GB of QL related documents, software and images!

This Sinclair QL internet site offers a whole lot for you to explore, download and try out.

The QL's software Environment is not a type of Unix. It's not a flavour of Linux. It's certainly got nothing to do with Windows or MacOS! The QL software Environment is its own thing - a very specialised 68K-based single-user preemptive multitasking operating system with a procedural structured BASIC interpreter as shell. So if you've not used it before, you will find it doesn't behave quite the same way as anything else. The QL community think it's better! We hope you enjoy your experience with the QL software Environment.

First there are those unique original documents dated 1982 to 1986 from the QL's inventor company Sinclair Research Ltd. Internal stuff like employee directories or preliminary documentation of the operating system, the launch press conference marketing material, brochures, magazine adverts, advertisement features, software developer's guide, user guide, service manual, you name it.

Second there are in-depth interviews and articles from this millennium reflecting the QL's history.

Last but not least there is THE DISTRIBUTION, a huge repository of QL related programs, documentation and images. Last updated in 2021 (RELOADED edition!), altogether there are about 4 GB of documents, software and pictures in the latest version of this massive collection called QL IS 30 2014 - THE DISTRIBUTION.
