Bob,
Right name, but I believe the wrong derivation. The "67" in CP-67 comes
form the fact that it ran on the S/360 model 67, the only production model
of the S/360 line that implemented Dynamic Address Translation (DAT) --
virtual storage.
Some would argue that was the first version of VM. Others would argue
that the line starts with VM/370, the first generally available version of
VM, which was first released in August of 1972. (FWIW, SHARE has been
celebrating VM's birthdays using the VM/370 release date as the origin.
Hence the 35th birthday was celebrated at SHARE 109 in San Diego last
Summer.)

The original version was called "CP 67" (I think), narrowing it down to 1967
or a bit before...
