Pointers to info

[sidneycadot]

Hi all,

I have my Neo6502 coming in this week, and I'm looking for background info.

In particular, I'd like to add Neo6502 support for my tool that does exhaustive instruction-cycle timing tests, for the benefit of people who want to make cycle-exact emulators (https://github.com/sidneycadot/6502-test).

The tool currently supports the C64 and Atari as hardware platforms; and I hope to add the Neo6502 as a platform too, which will expand the scope of the tool from 6502-only to the 65C02.

However, to support that, I need a way to do cycle-exact timing on the Neo6502. I suppose that will take either some custom code on the RP2040, or perhaps using some already available timing infrastructure that I'm unaware of.

The documentation at present seems mostly to be geared towards people trying to do BASIC programming and that kind of fun, but my goal is quite a bit more low-level.

I've tried to find a place or forum where Neo6502 users/experts gather but so far I haven't been able to. There's a Facebook group, apparently, but I don't do Facebook. There should also be a Discord server but that needs an invite, of sorts.

So my question, really: where can I get the kind of low-level information that I am looking for; or where are the experts hanging out who could answer a technical question like the one I have?
