I just found the classic book, "BASIC Computer Games (microcomputer edition)" by David Ahl, in e-book form:

PS: looks like another link for the same book, with direct HTML table of contents, here: http://www.vintage-basic.net/games.html
These games work on the PE6502! So far, I've personally verified checkers, eliza, and super star trek work (I tested with Integer BASIC)
Here's another version, "More BASIC Computer Games", also by David Ahl:

Also, these magazines had lots of articles and type-in programs/games back when the 6502 was "new"! My favorite was Compute! and Compute!'s Gazette. You can find those magazines and others here:
