Sorbus Computer: self-built 65C02 based computer for ~$15

[+SvOlli]

Hello!

In the last two months, I've created a self-built computer based upon the 65C02 and a RP2040 microcontroller only. Everything including PCBs and all code is open source.

 

The idea was to have a very simple system to teach about how the 65C02 works, as well as a platform to build very simple machines like the Apple Computer 1, which can already be mimicked. A bus system ensures that it's open for expansions.

 

An intended to be growing webpage has been set-up at https://xayax.net/sorbus/, all code is available at https://github.com/SvOlli/sorbus/

It would be interesting to see it  with a Riot and Tia emulating a 2600.

good work! - btw

Thanks!

 

Being a 2600 demo coder, this is definitely something that I want to try: a 2600 compatible machine that adds an ACIA, ROM for terminal software and some GALs for expanded address decoding, so a you could either get a machine with 63k of RAM also capable of running 2600 games.

 

But since there are also other project in the pipeline, I doubt it will happen within the next months...
