comparison of 6502, 65c02, 65816
Posted: Mon Dec 23, 2013 8:36 am
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:
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?)
- 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.
