Picocomputer 6502

Most of you have seen my project on YouTube. For the uninitiated...
It's a WDC 65C02 + 65C22 system with RP2040 chips running the video, audio, USB, and operating system. It can be built on a breadboard or on a PCB with 100% through hole construction. For some, it's a starting point for hardware experiments. For others, it's a complete system to explore programming.
Here's the full playlist:

Everything is Open Source. You can build it yourself, or have it built in China.

I probably speak for the vast majority of the forum members here - Never heard of you.

Welcome. I haven't heard of you either, so I went to your YouTube link and watched episode 11. I like the plexiglass covers.

Welcome indeed! I see I've watched some of your videos, so even though your name doesn't ring a bell, it's all good. Thanks for sharing your project!

See, that’s the thing that makes me suspiciously about these types of topics. They join up, first post is directing them to their YouTube channel and they are never heard from again.
It would be fine it they actually wanted to discuss their projects, but unfortunately it is clear that they do not.

Hm.
Part of me has a reaction like yours, J64C, so I think I understand the sentiment.
OTOH, it's hard to see that any actual
harm has been done. If anyone feels the newcomer is ignoring the discussion opportunity this forum presents, they're free to return the favor by ignoring the newcomer!
Or forum members may -- if they wish -- share the initiative for chattiness by asking a question or making a pertinent comment.

It does feel best to me always to start out by giving a positive reception. If the first response to a new joiner is something negative, or pessimistic, or pedantic, then it might well have the effect of putting someone off. And, not just the poster who started the thread - other visitors or lurkers who read the thread might be put off.
If you want a friendly forum, you have to be friendly. If you want people to post, and to stick around, you have to have given the impression that they'll have a good discussion here.

I have watched a few of his videos related to this project in the past but I took another look after his posting. His project and the Olimex Neo6502 project concept looks interesting. I ended staying up late and binge watched the whole series. Fascinating. Nice presentation.

Fascinating. Nice presentation.
Thanks for the report, Greg.
Reviewing the lead post, I'm inclined to also give credit to Rumbledethumps for making the entire project open source. "You can build it yourself, or have it built in China." Nice.

PS: Like many others here, I have never heard of Rumbledethumps before. And I suppose that means it's a good thing s/he posted!

Methinks these "one post wonders" with YouTube links is only about getting as many (YouTube) views as possible, nothing more... 'nuff said. And No, I don't bother clicking on the links.

I'm here. Happy to answer questions, but I didn't see any. If I'm just expounding, I do it in code, the documentation, or a video. And I'm old enough to ignore the off-topic stuff.

Glad to see you stuck around! For me the RP2040 is very interesting and potentially useful - just as previously people have used PICs or AVR as general purpose computational glue, I can see some people will do the same with RP2040 and/or Pico. Great to see examples of this!
(RP2040 also interesting because at least some of the board houses which offer assembly offer it as a standard part. And it's available in the Pi Pico, which is available and affordable, and can be fitted either as surface mount or DIP.)

For interest, there's a video here from a happy customer (Lee Smith):
Building A Pico 6502 computer kit and setting up Windows VScode environment.
(Reckons he's the first person to figure out how(*) to use Windows as the dev env for the Pico modules, as opposed to Linux. But I see there's now a repo
here with support. It looks like the project
releases include the uf2 binaries you'd need for the Pico side, if you don't intend to get involved at that level.)
Edit: (*) oops, see below.

Most people will never build the Pi Pico code (I'm guessing). Lee Smith's video is about the 6502 CC65 IDE built around cmake and vscode. You can, of course, build 6502 code with any tools you like, I'm just focusing on making everything use the same tools. The Pi Pico code is all C too, not C++, so you can explore the whole stack knowing only one language that's not assembly.
Here's a nice graphics demo made by Pugmaster Flash...
