[TUHS] Any good 6502 assembly references?

[Aron Insinga via TUHS]

p.s. And if you're writing your own simulator, that's cool. Depending on 
your interests, you may find an assembler to use for it in those places, 
and/or a monitor or tiny BASIC to put in your simulated machine's 
memory.  One of the sites below has a list of books, and archive.org may 
have some too.  [Long ago I wrote an assembler for the RCA CDP1802 
microprocessor and a friend wrote a simulator for it.  It's pretty 
different from the common 8080 or Z80 chips.  And when learning to 
program, I did both in BASIC-Plus for the DEC PDP-8 minicomputer.]
