This listing features a set of 10 COMPUTER PROGRAM PUNCH CARDS! Remember when computers were programmed with these? The cards are used, that is, they've been punched, but they're in excellent condition. They are marked with the emblem of NORTHWESTERN UNIVERSITY, and read NORTHWESTERN UNIVERSITY - VOGELBACK COMPUTING CENTER on them. Cool vintage computer item! I have plenty of these, and will combine shipping based on the total weight of all ordered.Please see my other listings for more cool collectibles!Payment is expected immediately for Buy It Now listings, and within five days for sales.
