GST 68K/OS operating system for the Sinclair QL    


A page dedicated to the GST 68K/OS for the QL. I am grateful to Urs König for collecting this material for posterity, and to Rich Mellor for pushing me into putting all this material online.

The GST 68K/OS system was originally commissioned by Sinclair for the QL computer, but for various reasons was replaced by the QDOS operating system by the time the QL was finally launched. GST went on to sell the 68K/OS as an option for the QL. The system comprised a small circuit board, various software on cartridge and a few manuals. Unfortunately, at this stage. I am not able to include much of the microdrive-based software as the microdrive cartridge format used by 68K/OS is not the same as that used by QDOS for the QL If anyone is able to copy the cartridges and can supply zipped copies or images of them (and any other software cartridges for the 68K/OS), I will gladly add them here.
