Hello all,
I'm curious, does anyone have any documentation on the CP11 card punch
option? From the '91 Edited Option Module List and various iterations
of the "Field Guide to QBUS and UNIBUS Modules" that it's:
1. A card punch,
2. A UNIBUS device, and;
3. It uses the M7824 board.
I'm most particularly interested in if anyone has any programming
information on it.
Best regards,
Christian

The 1975 option/module list shows CP11-UP to be a product from "Special Systems,
California", a "Punch interface for Univac 1710 card rdr/punch".
I had never heard of card punches for PDP-11 systems. I assume SSCAL is something like
CSS only more obscure. Most other DEC card punch products shown in that list are CSS
options, but there is another from SSCAL, the CP20-E which is a controller for the Data
Products 120 punch. Curiously, given the model designation, the "used on"
column says it's a PDP-15 peripheral. Both are shown as being the work of Bob Edwards
of SSCAL. The product status is "3 -- Custom build".

Good evening (at least it's evening for me when I'm writing this),

The 1983 option/module list agrees entirely. Looking it up, it looks
like the Univac 1710 was a keypunch. So it's not a dedicated punch
like a Documation P100.
The "Where Used" column definitely shows "11" so it appears to have
been intended for the PDP-11, and not the KS10.
Interesting, and curious.

So I'm going to guess then, that documentation for the CP11-UP is
going to be absolutely unobtainable. Unfortunate.
The 1983 option/module list lists two CP20-E_ entries, with
description "CP20-C_ + DIB20" and then 120V, 60Hz or 240V, 50Hz power.
The CP20-C_ entries just above list in their description "Documation
P100 100cpm punch, CP10-DA controller, a Terra Cotta coloured H9502
cab" and 120 or 240 power. There's also a CP20-D_ pair that is
equivalent to the CP20-E_ pair, but using the CP20-B_; and the CP20-B_
are the same as the CP20-C_, except the cabinets are in Blasi Blue.
So it looks like the CP20 is just a rename for the older CP10, paired
up with a DIB20 to let it run on a KL10B.
Regards,
Christian
