Someone in Minneapolis/St. Paul has quite a lot of IBM punched card
equipment up for sale. They mention 029, 077, 129, 514, and 526 -- it
looks like a large number of punches with perhaps one each of the 077,
514, and 526.
The auction ends in 8 days and is for "the right to contact me on the
above machines" -- so it looks like, if you want some or all of the
equipment, you'll have a chance to make a deal rather than take it en
bloc.
