- 6502 Machine Language Tables and Aids (techtinkering.com)
When programming using machine code there are a few useful aids that can make it easier to do. I have created a couple of tables for the 6502 that can make the process easier. They are based on tables found in ‘Machine Code for Beginners’, which Usborne have made available as a PDF for free.
- Hand Assembling to Machine Code on the Commodore VIC-20 (techtinkering.com)
I quite enjoy designing machine language routines on paper and then hand assembling them. For many people this would have been their only option until they got a more advanced machine language monitor or assembler. I want to show how to approach this and how to enter these programs on the Vic.
- Machine code (Wikipedia)
In computer programming, machine code is computer code consisting of machine language instructions, which are used to control a computer’s central processing unit (CPU). Although decimal computers were once common, the contemporary marketplace is dominated by binary computers; for those computers, machine code is “the binary representation of a computer program which is actually read and interpreted by the computer. A program in machine code consists of a sequence of machine instructions (possibly interspersed with data).
