folklore is that *IX (and numerous *IX work-alikes) came from
simplification of MULTICS.

some of the CTSS people went to the 5th flr of 545 tech sq and MULTICS
and others went to the 4th flr of 545 tech sq and the ibm cambridge
science center ... where cp40/cms was done (both MULTICS and cp40/cms
derivative of CTSS). science center was formed 1feb1964 ... 1982 SEAS

cms (cambridge monitor system) was originally developed running
stand-alone on 360/40 using 1052-7 operator's console for input/output.

the same machine had special hardware added to provide virtual memory
support which was used for the development of (virtual machine) cp40.

when standard 30/67 with virtual memory became available, cp40 morphed
into cp67 ... cms continued to run both on stand-alone 360 as well as in
cp67 virtual machine.

with virtual memory on 370, cp67 morphed into vm370 and cms was renamed
to "conversational monitor system" ... and ability to run stand-alone
was crippled.

The technology for the corpoate internal network was also done
at the science center ... some past posts

which was larger than the arpanet/internet from just about the beginning
until late '85 or early '86. Some recent references in this a.f.c.

there were several projects during the 80s to adapt CMS to GUI displays
... but it was somewhat anti-thetical to the corporate terminal
emulation paradigm. old post about running internal corporate adtech
conference spring '82 on various aspects of the subject:

one the presentations happened to be CMS running on MVS ... there had
recently been a new corporate strategy direction that CMS would be the
official interactive platform. CMS on MVS (as alternative to TSO) didn't
actually help things a lot ... since a lot of the problems are in base
MVS (not solely in TSO).

in this post
http://www.garlic.com/~lynn/2012.html#12 Who originated the phrase 
"user-friendly"?
also has ibm jargon definition for "bad response"

I even got a request from the TSO product admin if I would rewrite the
MVS scheduler (attempting to address some of the MVS structural problem
with providing interactive service):
