Just when we thought 2020 couldn't get any worse! We were about to re-open after many months of being closed but then disaster struck when a mains water pipe burst and flooded much of the ground floor of the museum. Sadly re-opening has now been postponed. Read More >>>

Machine code for action. Machine-code programs run very quickly, literally hundreds of times faster than the equivalent BASIC. And they are very powerful, enabling your computer to do things undreamed of by its manufacturer!
The ZX Spectrum uses a Z80 processor, and machine-code programs are written in Z80 assembly language. This book is a complete course in Z80 assembly language, right from the beginning. Written by an experienced teacher and programmer, it is ideal for anyone with a knowledge of BASIC and contains many complete-and useful- programs.
Assembly software. The assembly-language listings in this book can of course be hand assembled into machine code, but for speed and accuracy you should use the McGraw-Hill ZX Spectrum Machine Code Assembler program, available on cassette for the 16K or 48K Spectrum. All the program listings have been specially written to match this software
Since opening at the end of 2013, over 5,000 children have visited the Centre. These children deserve a space which is engaging and instructive, where they can feel a sense of adventure, exploration and surprise!
