Hi,
For those of you who asked to see the MITS
Teletype Interface board I mentioned a couple
of days ago, I've put a picture at
http://www.ibm1130.org/misc/mits-tty-interface.jpg
The molex connector at the bottom left below the relay
is where the data cable connects. The other end is
a DB25 connector, and the wires go to pins 2-6. Since
there is no connection to pin 7 (signal ground) it must
be current loop.
