Sorbus computers (Part 1)

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.

1. This is part 1 of my experience with the Sorbus computers. Just the parts and the info.
2. Next step, part 2, soldering!
3. A look at the hardware in part 3
4. Part 4 will be about the software, building it and downlaoding
5. Using the software: Apple 1

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 CP/M-65!

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

and here the introduction to the Sorbus concept and computer:
