6502 cheat sheet

Recommended Posts

On the atari.org.pl forum, an idea arose to print mugs with 6502 processor opcodes - such a gadget for extreme nerds.

For the purpose of this project I prepared graphics, which I think you may also find useful:

Source design in html format: 
https://mimuma.pl/opcodes/

 

mug print design:
https://mimuma.pl/opcodes/opcodes.pdf

 

A4 printout of the cheat sheet:
https://mimuma.pl/opcodes/opcodesA4.pdf

and the original thread on the Polish forum:
http://www.atari.org.pl/forum/viewtopic.php?id=19031

 

I hope that someone finds this useful.

Is white the only recommended mug color?

 

not really - vector graphics are transparent, so probably it will work on any light shade of any color.

For dark mugs you probably need some color inverted version - if you need that, I can prepare it for you.

I was thinking in a mustard yellow mug like the original reference card that came with the Assembler/Editor cartridge, but I don't know if something like that is available at local stores that prints whatever you want in them.

 

Anyway, I think that a color inverted version to be printed in black mugs could be appreciated in the community.

This is very nice!

Is it worth mentioning that bits get shifted in/out of the Carry bit with ROR/ROL (9-bit rotation, according to Rodney Zaks), but only into the Carry bit with ASL?

Also, I would have dropped the massive "Cheat Sheet" header and used a larger font (0.02ct).

Hi @bocianu,

 

   Apologies if I was a bit rude about dropping the background graphics (I have a habit of skimming posts). I just meant make them a bit less prominent so that you could use a larger font for the text, like a box at the start, like a drop cap. Alternatively, you could expand them and use them as a background graphic, which would let you have larger text and graphic.

 

   Unfortunately I don't have any talent at graphics, so can't draw out an example of what I mean.

This could also make for a great poster, just like a periodic table of elements, except it's 6502 opcodes and mnemonics :P

All the undocumented opcodes would fit the missing spots perfectly, similar to how heavy short lived elements are discovered and given new names every years, haha!
