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".
