Xerox 53D 6085 Computer
The Xerox 6085 was the successor of the revolutionary Xerox Star, first commercial computer to use a graphical user interface (GUI) with the familiar desktop, icons and a mouse.
The 6085 series was offered in models for network, remote (linked by Ethernet) and stand alone operation. The main unit was founded upon Xerox's Mesa 8 MHz processor which had 256 auxiliary registers and executed 48-bit-wide instructions. It also used an 80186 as an auxiliary processor.
