Re: 6502 VT100 Terminal(?)

Excitedly waiting for that to arrive. Written in 6502 ASM, python or c/++?
I think they put it on the wrong truck because it took an unnecessary tour of the USA. Seems back on track now.

It's C that should port well to CC65. I'm planning on renaming the file, so here's a long permalink...

Re: 6502 VT100 Terminal(?)

The Picocomputer I sent you has a VT-like terminal in it. It's not that bad looking back but getting started was hard. The deepest part of the hole is CSI with multiple arguments. I haven't filled out every command yet, but the state machine logic is complete.

I just thought that since you had done so much of the project in the Pico you could just take the next step and have a $4 6502.
Why me? It's your idea, run with it and submit a pull request. Not everyone needs a 6522 so "picos only" would be a viable configuration for some folks.

Re: Picocomputer 6502

If all you can think of are things that can be done with emulation, stick with emulation. Or just write it native.

If you want to learn about and tinker with real hardware, the RP6502 chipset is a strong foundation. You could, for example, drop the Pico VGA and design your own VGA system. Or do ...

Re: Starting a new 6502 design...VGA starting to come togeth

Coincidentally, yesterday, someone posted a port of Hunter Adams graphics code to the Picocomputer 6502.

How is your design going to differ from the Neo6502 and Picocomputer 6502 projects? You commented on a couple of my videos so I know you've ...

Re: Scrolling an SSD1306 OLED in 6502 assembly

I've remember finding your channel when you were still on a breadboard. I watch all the original homebrew content, when I can find it. I think there's a much bigger market than the algorithm knows about. Just not big enough to get its attention.

Re: Picocomputer 6502

There's only one PCB layout right now and it has all the 6522 GPIOs exposed on J1/GPIO. Options for access include cutting holes or leaving the top off or designing your own case or using taller standoffs or a ribbon cable.

Re: Picocomputer 6502

how to use Windows as the dev env for the Pico modules
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 ...

Re: Picocomputer 6502

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.

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 ...
