Information

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 availble 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.

First Sentence

At the very centre of your Electron microcomputer is a small inconspicuous chip called the 6502 microprocessor.
