Electron Assembly Language
==========================

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.
