Hey All. I got my hands on an old UTC O-27. Unfortunately, the silkscreening with all the pinout info has worn off! Would anyone happen to have one they could look at for the pinout info? Any help would be greatly appreciated. Thanks!

Thank you! I had already seen all the ones Whoops posted but didn't see the diagrams. This catalog I had not seen before. Huge help. Thanks again.
