Machine Code programming on the Sinclair QL

This book, Machine Code Programming on the Sinclair QL, gives the reader an insight into the machine code instructions that activate the Motorola 68008, the very powerful microprocessor upon which the Sinclair QL is based. The QL has already shown itself to be a neat little machine, both for games and in small business applications, particularly when used with the Psion software packages, Quill, Archive, Abacus and SuperBasic and other high level languages are not appropriate. This book shows the readers how to write programs and subroutines making use of QDOS, an operarting environment provided by Sinclair, and, with a knowledge of QL machine code and how to make QDOS save program writing time and effort, they will be in a much better position to improve existing programs and to make full use of the QL's processing power and hardware facilities.
