GNT 3601 tape punch docs?

I recently got one of these 3601's up and running. I was able to obtain
a .jpg scan of a manual page which shows how to set the 8-pos DIP switches
in the unit for baud rate, bits/char, etc.
I've attached it here (might not make it to the list so I've cc:'d the
OP directly too. I apologize for the quality but that is how I received
the document, which I was grateful for nonetheless.
It wasn't too difficult to get the serial port stuff sorted out but the
punch mechanism itself was a bit more of a challenge. The pins were
seizing in their raceways and ultimately stopping the motor which would
then cause an overcurrent shutdown.
I had to disassemble the punch, free each of the punch pins, properly
clean and then lightly oil the punch block and pins and after that it
worked real well. Too well actually, you can burn through a roll of
tape in short order with that thing ;-)
