A new series of books which introduce newcomers to the most widely used micros in the marketplace. The books assume absolutely no knowledge aboul computers and the reader is shown even the most fundamental operations such as "switching on" and "loading a program" The books lead the reader through simple programming and then onto graphics, with several programs which show how to achieve pictures and even animation. The books contain a number of specially written programs which show the full potential of these machines. The lexl is liberally supported by all manner ol useful diagrams and illustrations (including many black and white photographs ot the screen). The overall presentation is excellent. The printing, setting out and listings are clear and positively invite the reader to have a go. With the latest creation from New Generation £5.95 An action game that needs nerve and quick reactions! Hurtling through a void, your task is to travel as long as possible, scoring points along the way. Be careful though as you will have to avoid your own trail and those of up to four chasers. As trails are left you will have to thread your way through, but don't forget the more trails the less space for manoeuvring. You will be terminated when you finally get caught in 'the Knot'. For 48K Spectrum and compatible with Kempston, AGF and Mikrogen joysticks.
