This is very interesting to me. I was in sales for Bell in early 1970 and sold one of the first ComKey 718 systems anywhere. No modifications were supposed to be allowed, but it didn't take long before they were made anyway. The same customer who bought the 718 upgraded to one of the first 1434's a few months later. As I recall, this was the first key system with optional music on hold and it sold like flapjacks.
