IBM 1401
The IBM 1401 was a big machine that was used to help people do math and store information. It was made a long time ago, before you were born. It was a very important machine because it helped people do things that were very hard to do by hand.
Imagine you had to add up hundreds and thousands of numbers all in one go. That would take forever! It would be really hard, too. The IBM 1401 helped people do this kind of work much faster.
It was kind of like a giant calculator, but it was also different from a calculator in some ways. The IBM 1401 was huge, almost as big as your bedroom! It had lots of buttons and switches on it that people used to tell it what to do.
The IBM 1401 had something called "memory" inside it. This memory was like a big book that the machine could use to store lots of different numbers and codes. So people could put a lot of information into the machine and work on it later, whenever they needed to.
The IBM 1401 was a really important machine because it helped people in all sorts of jobs do their work better and faster. It helped people in banks keep track of money, and it helped people in big companies keep track of things they needed to buy and sell. Without machines like the IBM 1401, it would be very hard for people to do their jobs today!
