Easy 6502 by Nick Morgan
Code location: https://github.com/skilldrick/6502js Introduction In this tiny ebook I’m going to show you how to get started writing 6502 assembly language. The 6502 processor was massive in the seventies and eighties, powering famous computers like the BBC Micro , Atari 2600 , Commodore 64 , Apple II , and the Nintendo Entertainment System . Bender in Futurama has a 6502 processor for a brain . Even the Terminator was programmed in 6502 . So, why would you want to learn 6502? It’s a dead language isn’t it? Well, so’s Latin. And they still teach that. Q.E.D. (Actually, I’ve been reliably informed that 6502 processors are still being produced by Western Design Center , so clearly 6502 isn’t a dead language! Who knew?) Seriously though, I think it’s valuable to have an understanding of assembly language. Assembly language is the lowest level of abstraction in computers - the point at which the code is still readable. Assembly language translates directly to...
