This is the first computer I ever programmed, a Librascope LGP-30. A very early mini-computer. Not a desktop, but the size of a desk. It had 4096 WORDS of memory on a rotating drum. There was NO random access memory (RAM to you). The CPU clock ran at 120 KHz. It contained 113 triode tubes and 2340 diodes. It dissipated about as much heat as a toaster oven. In 1960, it cost $47,000. There is more processing power in your feature phone. And they designed aircraft with it!
