You're right - the 170 was the first use of main frame wire wrap at CDC. I've never seen any other machine that used twisted pair wire wrap. When I left the project, they were trying to defelop a machine to automate the wiring. It was not going well.
The earlier 6000, 7000 machines used twited pair with taper pins. Their wire mats were huge, more than 10 inches thick in some places. That was one of the problems they were trying to solve.
