root42Thanks to svolli I now own two fake 65C02 -- which are actually real 6502! Oh how the tables have turned... <a href="https://chaos.social/tags/mos6502" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mos6502</a>

Felix Palmen :freebsd: :c64:<a href="https://fosstodon.org/@jbqueru" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@jbqueru</a> <a href="https://mastodon.bsd.cafe/@gumnos" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@gumnos</a> <a href="https://mastodon.bsd.cafe/@mms" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@mms</a> Well, it has a PC of course, which is technically an "address register" 😏 not a general-purpose one though.Instructions are simple 8bit values (operation and mode combined to one opcode) and regarding which modes are available for which operation, I'd say you get quickly used to it. It's (partially) related to the purposes of the registers. None is really "general purpose", only A comes close, but yep, it can't do one thing X and Y can do: count.<a href="https://mastodon.bsd.cafe/tags/mos6502" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mos6502</a> coders use the "<a href="https://mastodon.bsd.cafe/tags/zeropage" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#zeropage</a>" in a way you'd otherwise use additional registers, which makes a lot of sense. The clocks for RAM and CPU are the same, RAM accesses need few clock cycles, and for the zeropage even fewer. There you can have your "address registers", 16 bits stored in little-endian.

C'est un montage qui permet de vérifier qu'un microprocesseur est vivant en présentant la commande NOP sur le bus de données (câblée en dur sur le circuit) et en regardant ce qu'il se passe sur le bus d'adresse : la commande NOP ne faisant rien le processeur passe juste à l'instruction suivante ce qui a pour effet d'incrémenter l'adresse, visualisée ici avec une série de LEDs.

ScrewtapelloIt finally occurred to me that my 6502 instruction database is unhelpful for writing an emulator: it records that certain instructions can take a variable number of cycles, but not the cause of the variation. As a result, it can't represent things like "an Absolute Indexed With X addressing mode takes an extra cycle for crossing a page boundary, unless the instruction writes a value, unless it reads *and* writes, unless it's INC or DEC". That information would have to be hard-coded into the emulator, and that undermines the values of having a machine-readable reference.So I'm going to have to expand it to report more detail about the variable cycles, instead of just adding them up.<a href="https://gitlab.com/Screwtapello/isa65xx" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://gitlab.com/Screwtapello/isa65xx</a><a href="https://teh.entar.net/tags/mos6502" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mos6502</a> <a href="https://teh.entar.net/tags/WDC6502" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#WDC6502</a>
