Hmmmpf... The first computer I worked on was an IBM 360 Model 30. It was bigger than the furnace in the basement. It had a whopping 32K of memory plus another 32K memory expansion unit the size of a dishwasher. It had no CRT display at all. It had a teletype that printed operator information on paper. You punched cards for input. It did have DASD but I don't remember the disk capacity. You had a deck of punch cards that you read into the card reader to IPL (boot) the system. It also had a whole bunch of little flashing lights and dials and switches that looked really cool.
