Ah-- the stories I could tell.. I was responsible for 3-4-5 VAX 11/785's around DC.. Sprint, NASA, ARMY, SPOT IMAGE(French NASA),Pentigon and it was a 32 bit computer. The CPU was 29 boards 3x3 feet. Ran on 2 -100amp 5 volt supplies. The back-plane was wire wrapped. It was a 0.9 MIPS machine. IBM was 1 MIP !! The MEMORY was another cabinet and pair of 100amp 5 volt supplies. Then came the peripherals cabinets.. To boot it, it required a LSI-11 ..a 5 board DEC computer and 8 inch floppies. The disk drive was 300Mb and as big as a washing machine.
Your Cellphone is more powerful, and I'm wow-ed with a week old Raspberry PI 400. I paid $70 for. Scary what if will be like in another 40 years. If only cars were less money as performance increased...
