Thanks to both of you. Sounds like a good plan of attack. I t will probable be a couple of weeks before I have time to try this but I will let you know the outcome. I’m going to take a nap now so you young whip-er snappers keep up the good work.
Thanks again

P.S. I have about 2,000 Hollerith coded 80 column punch cards in excellent condition do you think anyone on ebay would buy them?
