Hi Mark,
IIRC, NSSs didn't come on the scene until much later than Vm/370 Rel. 6.
Did you mean DCSS perhaps?

Hello, IBM mainframe enthusiasts:
Recently we have obtained images of some old tapes containing source code for
the original Cambridge Monitor System (CMS) from CP-67.
We can restore that source under VM/370 Rel. 6 CMS, running on older hardware or under the Hercules-390 emulator or the
new SIMH IBM360 simulator (that also simulates non-XA models of S/370). Several people are now working to recreate
CMS67 by re-assembling the source code, to geneate a nucleus and save it as a "named saved system" under
VM/370 Rel. 6, so that people can experience what "early CMS" was like, compared to the more
"modern" VM/370 CMS, (but under VM/370 vs. CP-67), e.g. by logging on to VM/370 and typing "IPL
CMS67" ...
For historical accuracy, the SIMH IBM360 simulator also supports the 360 model
67, and so we would really like to find a copy of the source code for CP.
IBM apparently made microfiche listings available for the CP component of CP-67, as well
as the CMS component. The complete microfiche set for CP-67/CMS was IBM form #
GYB0-0789-0, or for just the CP-67 listings on microfiche, form # GYB0-0592-1, and for
CMS microfiche listings only, form # GYB0-0593-1. If anyone can find a copy of
microfiche listings for CP-67 CP, we can re-create the source code from that, using IBM
microfiche; some shops had "COM" (Computer Output to Microfiche), so perhaps
someone may still have a copy of those listings in that format.
Also, If anyone recalls any IBM customer sites that ran CP-67/CMS back in the
day, where we might find possibly some old tapes containing those source
materials, please let me know here on this list, or you can reply privately.
(Even better would be to find a copy of the original CP-67/CMS distribution
tape for 360D-05.2.005, but due to age, etc., this now seems less likely.)
Thanks in advance for any help with these "computer software archaeology" and
historical restoration efforts.
All the best,
Mark S. Waterbury
