In 1970 in the bank where I worked.
All of the day's transactions were put onto a punch tape, using a piece of equipment like an adding machine.
Then we had to phone HQ numerous times before finally getting through and setting the tape running, on a big machine standing in the corner of the room, to transmit the info.
People from other branches, round about, had to bring their punched tapes to us, too, to be transmitted.
In 1973, I started a uni course in computer programming where I had to produce a collection of punched cards for each assignment and leave them with the computer room, which housed the huge computing equipment.
I then collected a printout the next day to find out if I had programmed correctly.
Unfortunately, I gave that up and had no more knowledge of computers until a college course, related to work, in 2002.
And the rest is history.
