Found that module number in a copy of the Option-Modules List. It shows that it’s a CSS item. That would explain why few have ever heard of it. I wonder what punch it used. I’ve seen people use CDC punches (415) as OEM devices. JWS mentioned someone interfacing a machine to a keypunch. That’s a bit of a desperation tactic, it would be extremely slow.
