The Sinclair QL

The Sinclair QL is a vintage computer first produced in 1983/4 and still used by many worldwide. If you are into retro-computing at all, the QL is an ideal choice of computer. It has a wonderful multi-tasking operating system called QDOS and a great on-board SuperBASIC interpreter for those who like to try their hand at the odd bit of programming! A newer operating system for QL is called SMSQ/E. The QL has spawned several compatible computers, including the Q40, Q60, Thor and Aurora, plus several QL emulators which run on computers as diverse as PCs, Amigas, Ataris, Macs (68K, PPC and OSX) and Linux systems. More information on the QL is available from the About The QL pages on this site.

Software Downloads

All of the software here is either freeware, PD, shareware or charity-ware unless explicitly stated otherwise. If you discover that any software on this site should not be here for copyright or any other reasons, please let me know as soon as possible so that the offending software may be removed. Similarly, if you discover any errors, please let me know so that I may try to correct them.

Broken executables, lost dataspaces and executable file headers after unzipping in Windows (program gives a "bad parameter" error after unzipping in non-QDOS environment), etc - have a look at this blog post.

Zip Files

Most of the QL software packages on this site are in zip file format - QL Zip and Unzip packages are available from the Archivers page on this site, and current versions can also be obtained from the website of the official maintainer of the QDOS Info-zip package, Jonathan Hudson. Note that if QL programs are unzipped using non-QDOS versions of Unzip, the QDOS executable file header will usually be lost and the programs may not work as intended. Information on the use of Zip/Unzip and transferring files can be found here.
