How computers have changed...
ENIAC was the first all-electric computer. It was first used in 1946 and cost about half a million dollars to build. It was designed to do mathematical calculations more quickly than a person. It could do 5000 additions in a second, but it slowed down to 38 operations per second to do division. It was enormous, taking up a whole room and weighing about 30 tons.
The Altair 8800 was the first "personal computer" and was introduced in 1975. It came in a kit that you had to put together yourself. It had no keyboard or monitor, so users had to flip the switches on the front of the box and watch the lights to see that it was running the programs the user was making.
