Quote from: Dominic_ContempraPhones on July 01, 2017, 12:22:11 AMThank you Alex for confirming I wasn't making this up ... SD-1A and SD-2A -- Bell threw everything out, and so did NE, so trying to put one together is hard. I was trying to fake it with SM-1 cards, but Joel wasn't so sure it would work. I bought one phone for $200 and I thought it was an ordinary Call Director. If you ever get a chance to scan that, send it to Joel. He sold the switch but it was intriguing. I didn't know SM-1 even existed.I was trying to fill it up with QUN20Ds ... these bounce from one lamp to the main switchboard. It could do 3-way. We found another digitone one

They had point to point cards so I said why don't we fake it, but he told me the intercom used a mini-crossbar of some kind.I used to work at Bell and I started digging through my archives. All I could come up with was SD-1A and 2A (in '67). SM-1 ... '79 with SL-1 like phones. Nashville. Confused the dickens out of everyone.This one drove people nuts too -- it's just a 2565 with two funky yellow lenses. Wanna bet?
