Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I came across the following:
RetroVGA - Raspbery Pico multi retro computer

Github link is here.
There is a minimal schematic in MCUME_pico/schematic/MCUME_REV1, but I don't see a complete one. The keyboard appears to be scanned by the Pico.

The form factor and packaging is neatly done.

This is not a pi pico.

Oops...
The article on Hackaday focusses on Teensy 4.1, and it has emulators for C64 and Sinclair spectrum.
But apparently there is a C64 / Spectrum emulator running on the pi pico ?
That would be great. Maybe Peter can look at the SID emulation, and put that in MMBasic. That would be great for the GAME pico. Especially the noise and ADSR (Attack, Decay, Sustain, Release) envelopes do things automatic that MMBasic would have to do with basic code (changing volume parameter in PLAY SOUND dynamically without Basic involvement).

Or the BBCBasic SOUND - ENVELOPE system which is the best I've seen (heard) ...
