The 6502 microprocessor changed the world

Released in the 1970’s, it was the reason that home computers were within the reach of many hobbyists

This app re-creates the 6502 CPU and some of the hardware that used it

This isn't a game (although games are included), this is an emulation of the 8-bit processor, complete with an assembler and some programming puzzles to solve.

Start with the most basic user interface you can imagine - six 7-segment LEDs and some buttons - to enter, debug and run your applications

Then upgrade to a display and keyboard, and use the built-in monitor program to dump memory, makes edits and execute your code

Can you run BASIC? Maybe

FORTH? Perhaps

Assembler? Definitely!

Don't think of this as a something "fun" or "enjoyable" in the traditional sense

Think of it as a puzzle: how on earth did those folks in the 1970's manage to do ANYTHING when computers were this basic?

Documentation is provided, but to get the most of out of this app you'll need to do your own research

Just like in the 1970s.
