[TUHS] Any good 6502 assembly references?

[Will Senn via TUHS]

Hi Aron,

On how it relates to unix, that's a bit of a stretch, but I'll offer 
this - in order to understand the v6 and v7 source code and Lions book, 
I spent 6 months with the 6502 and walked away with a much, much clearer 
understanding of the research unixes after returning :).

For refs, the manuals are hard to beat:

Look for MCS6500 Hardware Manual and MCS6500 Programming Manual fro high 
res, reproduced versions of the original manuals.

For lists of books and other resources:

My favorite books for doing stuff with it involve either the PAL-1 (a 
kim 1-alike) kit, or an apple iie emulation (on linux, I run apple iie 
via applewin, there are others):

and

Don Lancaster's Machine Lang Programming I & II if you're really new to 
how moving bits around a micro works:

I put together stuff on this kinda thing, too:

So if anyone knew any good manuals or open sourced design documents of the 6502 CPU I'd love to hear! I'm also open to other architectures that would be fun to write interpreters for.
