Not only the M21 but a whole line of proprietary machines sold to
government and small businesses. The os was called MOS and written in
a proprietary language Pascal+ with synchronization primitives like
monitors, semaphores etc. I never used it personally but heard quite
a bit about MOS while workinh in the Unix group of Olivetti. Apparently
MOS was only segmented.
