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
