Yep -- wire wrap was cheaper than custom PC boards in the
onesy-twosey world -- but was a lot of fun to debug. I've done enough
of that on my own hand-built boards.

I was also told that good wire wraps were more reliable than soldered
joints. By good, I mean by a certified wire wrap technician using
certified tools and materials. We used to use a lot of wire wrap on
space stuff for its reliability. Though I didn't work for the companies
that made the Apollo vehicles and lander, I have been told the main
Apollo computer was wire wrapped.
