The Sinclair QL Companion, Allan Boris
The Sinclair QL Companion
he Sinclair QL Companion is an essential handbook for the QL users, covering not only the Sinclair SuperBASIC language but the principles of structured programming, the use of sound and graphics and an examination of the QL's hardware facilities. For machine code programmers, there are sections on how to program the QL's Motorola 68008 microprocessor and an overview of the Intel 8049 support chip which is used to handle peripheral devices such as the QL's keyboard. This book is intended both for beginners in computing and for more experienced programmers and includes useful comparisons between the techniques of programming the QL and other popular micros.
