Does the
service manual contain schematics? If so, it should
be easy to find out which pins are used.
I am scanning the schematics right now and will post them
shortly. If somebody can take a look at them and decipher
them for me, that would be GREATLY appreciated!
The interface has a 15 pin male adapter, with
8 pins on top and 7 on bottom.
I have added a link to the schematics at the bottom of
the HP7202A Plotter page on my web site.
