I am looking for information for my recently acquired ASR33 that has
an Anderson Jacobson modem (ADT-233) built into it. I have retrieved
the documents for the base ASR33 from Bitsavers and University of
Queensland, but it doesn't look like any of the manuals describe the
modem. The modem is complete with the acoustical coupler. :-) The
modem does have a Teletype sticker on it and describes it as a UCC-6.
I need to know how to hook the ASR33 to my PDP-11 using a 20mA
connection. I am looking for user guides, technical details and
schematics.
Thanks!
