Was Acorn's RISC OS an under-appreciated pearl of OS design?
I was a huge Archimedes fan and still have an A310, an A5000, a RiscPC and a RasPi running RISC OS. But no, I have to disagree. RISC OS was a hastily-done rescue effort after Acorn PARC failed to make ARX work well enough. I helped to arrange this talk by the project lead a few years ago. RISC OS…
