A new development! A minimal 65(C)02 system, called Sorbus designed by Sven Oliver Moll (SvOlli). A minimal system with a CPU (like the WDC65C02) and a Raspberry Pi Pico.
This is part 1 of my experience with the Sorbus computers. Just the parts and the info.
2. Next step, part 2, soldering!
Features
- more a toy than a full featured computer
- open source
- keep it simple, stupid
- easy to solder
- expandable / modular
- run like and old computer → can mimic Apple 1
- run diagnostic monitor
- learn about 6502 → show CPU in action
- cheap: ~€15 / computer, including PCBs when buying refurbished 65C02s
- Runs Wozmon, CP/M-65, OSI Basic, TIM, Taliforth and more!
While being designed for use with a 65C02, it has also run 6502 and 65C816 processors successfully.
Since it’s using the RP2040 updating/changing firmware is easy. Not the standard Raspberry Pi Pico, but a variant (purple PCB) with all GPIOs exposed.
Here the homepage of the system
And here the github page with all design documents.

and I need at least a WDC65C02 and a 65c02, which I have in stock
