That's one of the next steps.

Now that I have microfiche/paper schematics,maintenance manuals, etc.. to
every DEC board/device ever made I actually found all the manuals to your
PRS01 paper tape reader.. I fact, I have a strong feeling I will be getting
a few. Please post back the exact model number as that will tell me the baud
rate.
They made two models: "A" version which is 20mA 300 baud. and a "B"
version
which is 20mA 2400 baud. I can post pinouts for the group if needed once I
get the full model number.
OT: so far I found two more PDP-16s, RSX-11B,C - papertape??, (I thought the
first version was "D"), and about a million other things I won't even try
to
list right now. I have also learned the art of stacking DEC handbooks 50
high...
Another thing I did not know was that there are 5 different PDP-8e
maintenance manual sets: Preliminary (3), Processor (3), Internal Options
(3), External Options (3) and Lab-8/e (1).
Finally, found a pile more of PDP-1 software including Spacewars (with both
patches) and OPSYS :-)
