|Lear Siegler ADM 3A|

Restoration project notes for Lear Siegler ADM 3A terminal S/N 21818 from late 1977.
The bad news: I cannot communicate with a known-working computer, no response from keyboard although box prompt is present.
The good news: The picture is in good shape.
I cannot get the computer to respond locally either. I tried to jumper pins 2 and 3 (I believe those are the ones).
Missing the dip switch cover.
Updates to come.

"..The ADM-3A transmits on pin 2, and receives on pin 3. Gnd is pin 7. .." My cable was pinned incorrectly. Terminal works. I assumed the pin configuration was similar to newer terminals. Rookie mistake! Thanks Bob Grieb for setting me straight.
