Someone from the CHM PDP-1 restoration team contacted
Western Numerical
 Control about having at batch of fanfold made. It was going to be on the
 order of several thousand dollars to have the paper maker WNC knows
 fire up the machine to do it. 
For a couple of thousand dollars, you can get a pretty darn nice
deluxe paper folder yourself. Some of them can do continuous folds.
