z80a coder discovering MOS 6502/6510
Hi all !
I'm interested in Commodore 64 from several years, but as I only know z80 langage (on Amstrad CPC 6128), I can't estimate the technical aspect of the demos I see under Vice (and I can't understand your technical posts on CSDb !). So, could you say me where can I find a kind of introduction to 6502/6510 assembly ?
Tanks !

(take a look at http://vanity.cpcscene.com/ to see what we do with our small z80 :) |

There is plenty of stuff (and links) on http://codebase64.org
That is where I learned c64 coding. |

"From scratch" was pretty cool; I remember watching the video when it came out. Good luck with the 6502, too. |

@Groepaz : this kind of 8080/z80/6502/6510 comparison will be very usefull for me to understand the mysterious Commodore world ;) I noticed some omissions in the z80 column, but maybe this page is old, or always under construction or wasn't made to be exhaustive... For example we can swap to the secondary registers with the fast "EXX" instruction, we can swap between the two akku with "EX AF,AF", all the bit-shifts and conditional branch you write in the GameBoy column are available on z80, and there is some illegal opcode... If you are interested in completing your array take a look at (or ask me, it will be a pleasure to help you) :

(it's the technical-wiki reference for CPC users)
@Graham : thanks too (and I love your job in Oxyron !) |

"From Scratch" is indeed wicked stuff. Gotta envy those psychedelic colors. The sound hurts my ears a bit though, it's no SID after all :-D
