Eons ago, I and my colleagues were tapping on the keyboards of VT-100 terminals attached to a computer running VAX/VMS.
Pencils clenched in our teeth?
Uhhh ...
No.
i did that back in the early 90’s don’t know/remember what kind of terminal it was.
kind of like sitting in front of a kodak microfilm machine loading documents into it. still had no pencil in my mouth.
maybe just a pen in my pocket.
