From the April 10, 2023 Daily Bulletin:

Years ago, when Nancy (BA ’78) and Allan McCalder (BA ’78) came back to the University of Waterloo for a tour, they knew their kids needed to see the computer.

If you were also a Waterloo student in the 1960s or 70s, you probably understand why. At that time, the Math and Computer building (MC) housed the largest computer in Canada, the IBM 360 Model 75. It was housed in the centre of MC, and any student or passerby could peer in through the windows to see its gigantic size.

“The whole main floor was a computer,” says Nancy. “It was humungous. We said to our boys, ‘We’ve got to see this computer.' They loved computers, and so we went to the math building and looked in the room.”

Nancy and Allan were shocked at what they saw.
