Does anyone know of a web page showing the differences between the NMOS 6502, the 65c02, and the '816? I have everything on paper, in different books and appendices and ap. notes, and various links, but there ought to be a single web page showing all of it in one place:
instructions
addressing modes
op codes
extra signal pins and their uses
NMOS bugs, corrected on CMOS
differences in invalid writes in R-M-W instructions
differences in reset and interrupt behavior
differences in speed, bus-driving strength, power consumption, clock requirements, etc.
and I'm sure I'm forgetting something.
I don't find any such complete page on 6502.org or the wiki. I was thinking of writing it myself, but I'd rather find a well done already-written one. Next easiest would be to make it a short page linking to other pages that address individual items in the list above, like Bruce's 65C02 Opcodes article at http://6502.org/tutorials/65c02opcodes.html. Some of them are in the Eyes & Lichty manual, some in the data sheets, and some in other .pdf sources, but then the reader has to download the whole thing and find a particular page you direct him to. (I think there's a way to add something to the URL so the tab with the .pdf goes right to the desired page. Can someone tell me how to do that?)
It doesn't have all the information, but seems to cover instructions/addressing mode/timing.
(I have a modified version of the table from this page that I used to extract information for use in my assembler. The modifications were for typos, and for invalid HTML structure, IIRC.)
