CTSS online/interactive timesharing:
https://en.wikipedia.org/wiki/Compatible_Time-Sharing_System

By July, 1961[5] a few time sharing commands had become operational on
the Computation Center's IBM 709, and in November 1961, Fernando
J. Corbató demonstrated at MIT what was called the "Experimental
Time-Sharing System". On May 3, 1962, F. J. Corbató, M. M. Daggett and
R. C. Daley published a paper about that system at the Spring Joint
Computer Conference.[6] Robert C. Daley, Peter R. Bos and at least 6
other programmers implemented the operating system, partly based on the
Fortran Monitor System. The system used an IBM 7090, modified by Herbert
M. Teager, with added 3 Flexowriters for user consoles, and maybe a
timer.

The IBM 7094 and CTSS
http://multicians.org/thvv/7094.html

then some of the CTSS people went to the 5th flr to do MULTICS
https://en.wikipedia.org/wiki/Multics

Initial planning and development for Multics started in 1964, in
Cambridge, Massachusetts. Originally it was a cooperative project led by
MIT (Project MAC with Fernando Corbató) along with General Electric and
Bell Labs. It was developed on the first GE 645 computer delivered to
MIT in 1965.

Other CTSS people went to the science center on the 4th flr and did
cp40/cms (using modified 360/40 with hardware virtual memory support)
http://www.garlic.com/~lynn/cp40seas82.txt

which morphs into cp67/cms when standard 360/67 with virtual memory
becomes available 
https://en.wikipedia.org/wiki/CP/CMS

above history somewhat garbled. There was CP67 "L" floor production
system at Cambridge (and I distributed/supported for othere internal
datacenters). There were the "H" updates to CP67 "L" ... which provided
optional 370 virtual machines (new instructions and slightly different
format for virtual memory tables). And there was the "I" udpates to CP67
"H", which was CP67 modified to run in a 370 machine instead of 360/67
machine. CP67I was regularly running production in CP67H virtual
machines a year before the first 370 engineering machine with virtual
memory support was available. CP67I with San Jose updates to support
3330 disks & 2305 fixed-head drum (CP67SJ) ran production on large
number of internal 370s ... well before VM370 was available.

in 1968, there were some science center people joined
NCSS to do CP67/CMS commercial online timesharing service bureau
https://en.wikipedia.org/wiki/National_CSS

and some other science center people joined with some Lincoln Labs
people to form IDC CP67/CMS commerccial online timesharing service
bureau ... especially IDC quickly moved up the value stream specializing
in services for the financial industry.

trivia: one of the people from the 5th flr joined IDC (out in waltham)
... and then a decade later did spreadsheet:
