jjimm, X-bar? How about the old step switches, and polar relays, how I loved them, of course, 1A1.
txfoneman, we had one of those mounted on a wall!! When we took it down took 3 men and a fork lift.

Just wanted to add, the worst sound in the old offices, X-bar, step was silence.

Hey Guys,
I am a telecom student about to enter my 2nd year of a 2- year program. I thought you might find it interesting that at my school, we still do about 2 weeks of lab work on the 1A2 keysystems. We have copies of the schematics, are expected to know & understand them, and are given a 3-line system to "install" and configure for various situations. Our instructors feel that we should have a knowledge base that includes everything from legacy to modern equipment.
I loved working on these old systems, and some fellow classmates even fixed some internal wiring problems with their systems.
My teacher did have 1 main instruction: Don't mess with the wirewraps in the back....or die...lol!
Those wirewraps looked mighty impressive!

There was a 770 at the old Ferry Building (now called the SF World Trade Center) in San Francisco, which was one of the working models for the schematics I learned on. It was good to learn the concepts, which can be applied to today's technology, still.
