A visual reference to the 65c02 instruction set.

Inspired by https://pastraiser.com/cpu/6502/6502_opcodes.html and implemented with https://d3js.org/

The op code data in opcodes.json was scraped from the table above using scrape.py and then augmented with 65c02 instructions based on http://6502.org/tutorials/65c02opcodes.html

The current version is served at https://patricksurry.github.io/periodic-65c02/ and should look like this:

To serve locally for development, use python -m http.server and browse to http://localhost:8000/opcodes.html
