Re: Anyone but me remember "bursting" mainframe print jobs?
Yes, though our machine had blades rather than cotton strands and so was more properly called a "guillotine".
We got all the carbon paper out using a machine called a decollator. 3-5 part went in one side, paper fanfolded into the hoppers and the carbon was rolled up on forks.
Also good for catching ties, which were mandatory as we were on the Director's Suite. That shop was the DP equivalent of Grace Brothers in every way, and DP was run by someone who was a dead ringer for Dilbert's PHB - also in every way.
Oh how we laughed (On Fridays when discrete laughter was permitted and not a firing offense).
