[GreenKeys] terminal set AN/SGC-1A, teletype writer AN/UGC-129 and receiver R-390A

[Patrick]

I have gotten the subjet units and would like if someone can helkp me with the following:

How to power the teletypewriter (which pins/terminal)
How to connect the terminal set to the teletype writer (terminals and pins) have already connected AC cable to it.
How to connect the audio output of the R-390 to the terminal set.
Where to abtain ribbon and spools for the teletype writer


Any and all help would be appreciated.
