[GreenKeys] Teletype with Coupler - ADT-233

[Jeffrey Golas]

So I had a chance to dig into this ASR-33 I got with the built in coupler, and have now removed all the dangly switches and diy rs-232 mod, and while it definitely needs some love, it seems to decode and print OK from paper tape.

Questions:

Would anyone happen to have a manual/schematic for this? Its an Anderson Jacobson ADT-233 (thats whats on the badge of the teletype), but Id bet a DC230 modem/coupler is nearly identical if anyone has documentation for that too. Other than the coupler its a basic Asr-33 with a UCC-6, but Id love a wiring diagram.

On the wiring front, theres an unused plug in the UCC area, and going by other docs I think this is how the coupler gets wired to the TTY, but Im not sure, hence why Id like a diagram. The dc230 stuff I found describes a harness with the exact colors at the plug, connecting to the terminal strip. 

The same documentation mentions some ttys may lock their keyboards, how can I tell if thats the case with this? The h-clip doesnt budge and whole the keyboard moves (ish) it doesnt register any keypresses. Maually triggering the distributor does work though.

Last question; it looks like plug #1 carries the data buss that other plugs like #6 carries, was #1 just for misc use? None of the schems I have even mention it.

Thanks!
