Prime sold a subsystem called Information which was more-or-less
a clone of Pick, and from the mid-80s on, this may have been its
best-selling product (I'm certain it was in the UK). But prior
and subsequent to that, Primes were very prevalent as university
timesharing systems, and laboratory support systems.

The Primos operating system had its initial roots in an older
OS they called DOS, which had some legacy from another Prime
OS, RTOS, which in turn was a port or re-implementation of
Olert/4 and/or SAMTRAN, a Honeywell Controls OS funded by
NASA. Beginning with the P400 processor, Prime systems were
16-bit data/32-bit address versions of the Honeywell Multics
architecture (which was 18-bit data/36-bit address).
