A UNIX Based Device Driver for the Vector General 3404 Graphics Display System.

Abstract

A device driver for the Vector General 3404 Graphics Display System was installed under the UNIX version seven operating system on a PDP11/60 computer. This was accomplished by modifying an existing device driver which was designed to run under version six of the UNIX operating system. The major topics addressed in this report are the C programming language, peripheral device I/O processing under UNIX, the hardware interface between the PDP11/60 and the graphics display system, the graphics display system itself, and the existing device driver software. Structure charts were used to document the design of the UNIX peripheral device I/0 processing software and the design of the device driver software. Modifications to the original device driver were easily accomplished due to the top-down modular design of the original software. UNIX provided a straight-forward interface for adding the device driver software to the system. (Author)
