Xerox Alto
The Xerox Alto was the first computer to use a mouse driven graphical interface. The invention of the Xerox Alto majorly effected the way computers were made, given the mouse driven interface and simplistic design. These computers are extremely rare and fetch up to $30,000 in auction. The reason that Xerox made these was to give universities and organizations the strength and power they needed to get more things done and start to evolve into new stages of teaching and organization.
