This may be helpful and can be downloaded from my blog. I'm calling this the beta version, so comments are welcome.

Welcome, Mike!

I see "Mike's Hobby Blog" features a range of interests, including "computers, trains, wargames, fish, railroads and more." Good stuff! -- I know for sure there are members here that share some of those pursuits. (Hmmm. Railroads and trains, eh? I guess there is a distinction... )

I didn't proofread it, but your 6502/Apple 1 quick reference certainly looks clean -- a very nice presentation. As for being beta, I know my own "cheat sheet" files are never really finished!

cheers,
Jeff

Great reference. Welcome, Mike! I've been inspired by your work over the years.
