A software compiler for the Sinclair QL, TURBO comes with a hefty manual, people new to this software sometimes just need a quick reference of the key features, hence the name. Actually, on reflection, seasoned users of the TURBO manual would probably also prefer to use a quick reference manual too. Hey, the book is for everyone.
This is an e-document of the original manual that came with the software and has been updated slightly. Both this and the software are free to the general public, the software availability is indicated in the manual.
The purpose of re-publishing this e-document (QL Turbo Quick Reference guide) is to make it (and others) available to the widest possible audience especially those not familiar with retro computers or operating systems from the early 1980s onwards. The Sinclair QL was such a machine, some say ahead of its’ time with a multitasking operating system QDOS, and probably the best BASIC in the world Sinclair QL SuperBASIC.
