The Prime 50 Series architecture is a segmented one, with memory divided into 64 kiloword units. The segments are divided into four groups, with each group addressed by one DTAR (descriptor table address register). The groups contain segments numbered (in octal) 0000-1777 (PRIMOS proper), 2000-3777 (shared code and data), 4000-5777 (user programs) and 6000-7777 (per-user kernel data and stack). Use of these segments needed to be coordinated; Prime reserved some of the shared segments for Prime software products for example, and others for customer use. Memory access protections prevented user processes from accessing some parts. Not all segment numbers were allocated, or even allowed for in the mapping schemes. PRIMOS periodically grew new mappings for additional segments.
The list below is of unknown vintage and source. Based on personal knowledge (or more accurately, lack of same) I would guess this to have been updated by BORIS staff in 1990 or later. It might be possible to refine its vintage by comparing its DTAR0 segment usage to PRIMOS source code, if enough different versions were available. (They're not, currently.)
