I was surprised to find this 'old computer' running the UK's air traffic control system when I joined the CAA in 1989 - it used an IBM 9020D which is a triplex (3) model 65 S/360 with two model 50s as I/O 'elements' for radar data processing. It was replaced the same year by dual IBM 4381s; gone were the card reader and ounch, though we continued to use mag tape.
