I believe the Model 37 is the RS-232 Teletype. (Is it based on the 33, or 35?
I don't know.)

If you have a working UNIBUS PDP-11, there are still 20mA serial interfaces
avalable for it. I have a DL11-C (M7800-YA) you can have for what I paid for
it (a song, just about), and someone on eBay has a DZ11-C (M7814) for sale
for cheap; someone else there has the breakout panel for it.
