trivia: science center wanted to get a 360/50 to modify for virtual
memory, but all the extra 360/50s were going to FAA ATC ... and so they
had to settle for 360/40 ... they implemented virtual memory with
associative array that held process-ID and virtual page number for each
real page (compared to Atlas associative array, which just had virtual
page number for each real page... effectively just single large virtual
address space).
the official IBM operating system for (standard virtual memory) 360/67
was TSS/360 which peaked around 1200 people at a time when the science
center had 12 people (that included secretary) morphing CP/40 into
CP/67.
