[GreenKeys] ASR33 modem

[teletypeparts at aol.com]

Barry,

P2 Molex is paralleled to the terminal strip for the TTY input/output connections.  When I get to my other computer I will send you 2 pictures that you can print and tape together which show the 33 data connections and strapping for 20/60 MA and full or half duplex.

On my ASR-33, an Anderson-Jacobson acoustic coupled modem (ADT-233) is
nstalled.  Does anyone have information on this modem?  I have
oogled around, but have only come across the patent for the device,
ut no further information.
I am looking to connect the TTY up to my ancient PDP-11 computer, but
 need to be sure the modem is sufficiently disconnected for the
irect connection.
Thanks!
