Electron Assembly Language

the long version

So you can drive your Electron in the 'first gear' of BASIC - how about moving into 'overdrive' with assembly language? Get things moving faster with this guide to machine code programming, which includes: * binary to decimal to hexadecimal conversion * mnemonics * the accumulator, index registers, assembly delimiters * the status register and carry flag * addressing modes * addition, subtraction, multiplication and division in machine code * the stack and how to use it * subroutines - assembler equivalents of BASIC GOSUB and RETURN * machine operating system routines and their uses There are programs throughout the book giving you many opportunities for 'trial-runs' at any stage. Also included are Appendices giving ASCII codes, assembly language equivalents of BASIC statements, the instruction set and opcodes for the 6502. An Electron Utilities tape is available to help you 'accelerate' more smoothly. This is a parallel volume to 'BBC Micro Assembly Language' by the same author, rewritten specifically for the Acorn Electron.
