Personal Computer Coloring Page

The first computers filled whole rooms and belonged to governments and big companies. That changed in the 1970s, when small, cheaper computers could sit on a desk at home. The Altair 8800 of 1975, built by Ed Roberts, came as a kit to put together yourself, and in 1977 the Apple II, the Commodore PET and the TRS-80 came ready to use.

The computer mouse is even older. Douglas Engelbart built the first one in 1964, out of wood, and people called it a mouse because the cord looked like a tail.
