Chuck Peddle is an absolute legend. The 6502 was my first microprocessor love, thanks in part to this book: https://archive.org/details/Programming_the_6502 https://archive.org/details/Programming_the_6502 ("Programming the 6502" by Rodnay Zaks - Actually I read the French edition by Sybex, I didn't read English at the time), and to the awesome computers that used it: Commodore, Oric, and of course Apple (I owned an Oric-1 a few years later).
