This book was commissioned withing a few weeks of Interfacing Projects for the BBC Micro. I approached Chester-based Shiva Publishing with the idea and after a meeting at their offices the book was contracted.
The book was all hand written, as at the time I still could not afford to buy even a dot-matrix printer.
The book was delivered towards the end of 1983 and was published in February 1984.
