Hey there was a lot of skill in fluffing up the "Do not bend, mutilate, or spindle the cards", for the IBM 101s of the Workmen's Compensation Board, most of them returned checks from pissed off injured construction workers, or miners dying from Black Lung or Silicosis afflictions. The worst cards couldn't be duplicated and would take me into the card entry room full of nubile young ladies where I could exhibit my charms, and bless the angry workers who had "bent, spindalled or mutillated" the IBM cards on which their checks were issued. On occasion I would "bend, spindal, or mutillate a card myself when putting on a move to an exceptionally attractive keypunch operator. Ah, those were the days, my friend.
But your the only person I know that has a knowledge of those IBM card sorters. Damn. You could have 5 to 10 years on me.
