well I located the machine and it turns out that the connector closest
to the corner is used. we made a nullmodem cable going to a db9
connector and we grab the papertapes on a 600/1200 baud setting as
handshaking is somewhat broken on the pc side and we want to be shure to
get al the bits. :-)
Our capture of pdp-8 tapes is here:

but at the moment, I
cant to remember on which connector it went. i think is was the
connector going to the terminal, not the computer one. via the dip
switches on the bottom you can preset three speed settings, available at
a switch on the top. I will take a look wednesday when i'm back at the
museum.

I have a box of old HP paper tapes to read,
and am having an awful
time trying to build the right serial cable to connect a GNT-4601
reader/punch to a Linux PC. Does anyone have a known good cable diagram
and stty settings that will work? Thank.
