in late 68, university started a project to clone an ibm mainframe controller ... reverse engineering the mainframe channel interface and building a channel interface board for interdata-3 ... and programming the interdata-3 to emulate the mainframe controller.
Interdata was eventually bought by Perkin-Elmer. In the late 90s, I ran into somebody at RSA conference in San Franciso, who mentioned that he made a really good living in the early 80s selling the boxes to NASA (and claimed that the mainframe channel interface board looked like it had been designed in the 60s and never updated). In the same time-frame I visited a major credit-card "acquiring" datacenter (i.e. million or so of those merchant point-of-sale credit card terminals connect into) ... where the incoming lines were being handled by Perkin-Elmer ("interdata") boxes.
in june 68, a commercial company was formed to offer commerical timesharing based on cp67 platform
... technology based on virtual machine work at the science center on the 4th flr of 545 tech sq
... multics was going on 5th flr of 545 tech sq.
fall of 68, a second commercial company was formed to offer commercial timesharing based on cp67 platform.

start of 1968 plus 1, boeing formed BCS (boeing computer services) with the objective of moving all boeing data processing into BCS. During spring break 68 plus 1, I was con'ed into teaching a one week computer clbutt to the BCS technical staff. Then that summer they con'ed me into taking a job as BCS management (i got badge that got me into the management parking late at Boeing hdqtrs across from Boeing field). core of BCS datacenter at corporate hdqtrs was cp67-cms system.
re: from keykos history, here is account of Tymshare offering vm370 based timesharing starting in the early 70s from above: About that time Tymshare had become profitable and we could look beyond the...
later in the early 70s, other companies like tymshare was using it (or its follow-on vm370) to offer commercial time-sharing services.
here is reference to Gary Kildell using cp67-cms at NPG in '72
