i'm bill worthington, it onto here at the computer history museum in mountain view, california. i was a programmer for the 1401. back in the timeframe we are looking at, in the 1930's, 19 is 1950's, -- 1940's, each hole representing a piece of information whether a 01, 2, -- 0, 1, 2, 3. or it could be alphabetic information. this is the means of storing information, it was the key for every business in the 1930's, 1940's, 1950's. when i started working for a bank on the east coast where they were in need of programmers, but their business ran on punch cards, 1401's were installed. what only go ahead, and we need to get some data ready? we are going to need a volunteer also to comment. why don't you give a hand here? installed. what debbie has done is to type her name into the card, making holes for debbie as the name in the card. all i'm doing is putting debbie's card into the deck. what i have here is a program, it's a deck of cards, they were called ibm cards at the time because ibm had a monopoly on punch cards. you ready to be right. i will hit the low button to the program.
