Once upon a time, in a galaxy far, far away, I spent several happy years working for the legendary Acorn Computers and their near mythical set-top box subsidiary, Online Media . We did some seriously cool, groundbreaking stuff there, including being (arguably) the first to stream video over internet protocols. All the computers ran on RiscOS , a homegrown, lightweight, adaptable operating system for ARM processors. Alas this time came to an end, and Acorn disappeared, but their legacy lived on. RiscOS carried on, supported by various companies. I had mostly forgotten about it until now. An old colleague recently mentioned that in 2006 a group of ex-Acornites started a new company, RiscOS Open Limited (ROOL), dedicated to maintaining the operating system and take it forward. The OS is still available, and supported. So do take a look, and if you have an interest in RiscOS then do consider helping them out.
