Answer: The IBM 305 RAMAC
The IBM 305 RAMAC, otherwise known as the first computer with a hard drive, was truly revolutionary. It might not look like much to modern eyes, but this giant machine changed the way we work with computers forever. The RAMAC came out in 1956, which is around when this photo was taken. This model was only accessible to private companies and the U.S. Navy, but it paved the way for personal computers and even our handheld smartphones.
