Manufactured from 1986 until 1992, the Apple IIGS was the first truly multimedia Apple computer. Steve Wozniak was involved in the design and layout of the computer. Based on a 16-bit CPU, the IIGS offers significantly improved graphics and sound compared to earlier Apple II models, while being fully compatible with them (via the Mega II chip). The computer was sold for $999 or about $2,640 in today’s money.
Designed in 1972 and released in March 1973, Xerox Alto is a revolutionary machine built by Xerox PARC (Palo Alto Research Center). The innovations brought by Alto included the first-ever Graphical User Interface, LAN, optical mouse, and high-res bitmapped display. The Alto was also the first computer to use a laser printer, an invention also by Xerox. The Xerox Alto wasn’t a commercial computer, it was a research prototype used by universities and the Xerox PARC itself.
