aka, official product for the 360/67 virtual memory (i.e. pretty much
360/65 with hardware address translation added).

science center had been hoping to win project mac ... with virtual
memory system. project mac (aka something of followon to ctss) went to
GE & multics.

the science center decided to do a virtual memory system anyway ... they
tried to get 360/50 to modify with hardware address translation ... but
all the spare 360/50s were going to air traffic control system ... so
they had to settle for 360/40 that they modified ... and built (virtual
memory, virtual machine) cp/40. when a 360/67 machine was finally
available, cp/40 morphed into cp/67. folklore is that at some point,
there were a 100 people working on tss/360 for every person working on
cp67/cms (& something about large number of people contributing to
extremely bloated software).

some amount of gory details are available in melinda's virtual machine
history found here:

bitsaver has some number of old tss/360 documents

as well as 360/67 functional characteristics

later tss/370 effort got a special deal with at&t to do a stripped down
low-level tss/370 kernel (SSUP) that would have unix layered on top.
