This book has been a nice resource for learning 6502 assembly. I’ve spend a lot of time just scrolling through the document looking for things I need since the PDF isn’t searchable and the full-text version is somewhat unwieldy. I took a shot at making a quick layout of the index here. Hope this might help someone else too.
