Operating System
The Sbc-3 has everything needed to run a proper OS, so porting something like NetBsd or Linux to it would be a Good Thing(tm)
Possible Candidates
- (NetBsd)[https://www.netbsd.org/]. Still very active.
- (uCLinux)[https://sourceforge.net/projects/uclinux/]. Need to take a closer look.
- (Gloworm)[https://github.com/transistorfet/gloworm]. This might be a good place to start as it's fairly basic and it doesn't look like too much effort would be required.
