You are correct that its a dumb terminal that used to connect back to the Trumbull, CT data center via leased Western Union lines. I do have the schematics/manual, but they are under some heavy books for a few weeks to de-curl them. I guess, first I need to recap the thing. The 3" green phosphorus CRT doesn't work - hopefully recapping it will fix that. Then I want to figure out the messaging format and attempt to hook up the AM/P connector to a Raspberry Pi and then the Pi to Bloomberg in order to pull in live quotes. I will need help identifying parts suitable for replacement, tips on getting the ancient CRT back on if recapping doesn't work, and thoughts on how to decrypt the ancient messaging format and pinouts to bring her back to life with live quotes.
