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.
