  My understanding is that it ran a small
single-user disk-based OS
 and possibly a realtime OS... Bill Poduska and David Udin & Co.
 worked with these a bit and based the architecture of the first
 Prime Computers on the Honeywell 316. I always assumed that the
 early Prime DOS and RTOS were made to resemble something they'd
 used before (they weren't ready yet for their magnum opus).  
 According to what I've read in preparation for picking one up,
 later Prime systems also have the instruction set(s) for these 
 in the core. 
Oh yeah, they've got the same sector-zero-relative addressing mode;
I mostly worked with the later 50-series instruction set, but I did
a little disassembly of some older code, and it was an enlightning
experience.
