Still remember my first exposure to the IBM 360 in 1971 when this was the memory storage system with a maximum capacity of a whopping 400MB!

20 years earlier, there was Princeton’s IAS machine:
Those 20 tubes sticking out at you on the bottom (there are 20 more on the other side) are Williams tubes, which stored memory as constantly refreshed spots on a CRT screen. 5 KB all told. The whole computer had about the same throughput and memory as is dedicated to placing the cursor on the screen of your PC nowadays.
