I ported the late, lamented Prex operating system to the Cybiko. It was a bit cramped but worked well enough to... well, okay, it actually worked really badly, but it booted a shell and you could run programs. It'd probably run Fuzix quite well. (Prex is Minix-like and moderately memory-hungry.) It used an H8 microprocessor which was really rather nice. Tight code and interesting to write assembly for, and the gcc port was decent. The hardware was interesting if useless; there was a not-quite-proprietary wireless protocol (it was an off-the-shelf low-speed wireless module), a small and primitive LCD, the world's most terrible keyboard (it was genuinely painful to type on), but a decent battery life. The Prex port is probably useless, but it does come with a Linux tool to upload programs via the Cybiko boot loader, if anyone's interested: http://cowlark.com/cybiko/ http://cowlark.com/cybiko/
