Many years since I worked on a Prime box. When I was slim and single
and my knees didn't hurt! Primos was an outstanding Multics-derived
O/S, and Information was a superb dbms, but Prime Computer got itself
into that poison-pill fight with MAI/Basic 4 after the ill-conceived
Computervision acquisition. And that was the end of that.
