Patent number: 5274766Abstract: A combination keyboard and keyboard/mouse controller system is capable of use with different types of personal computers, using either a keyboard input alone or a keyboard/mouse combination. The controller is configured with a hardware transceiver in it, and includes interconnections between an accumulator and a microsequencer portion and a transceiver for effecting the transfer of data to and from the computer and the keyboard or keyboard/mouse combination. The configuration of the controller circuitry is such that logic gates and multiplex transmission gates are employed between various ones of the input terminals to which signals are applied, and output terminals to which signals are provided. These gates interconnect at least some of these terminals in different combinations in different modes of operation of the controller system, depending upon whether a computer uses a keyboard alone as a data input device or is operated with a combination of a keyboard and mouse.Type: GrantFiled: September 14, 1990Date of Patent: December 28, 1993Assignee: VLSI Technology, Inc.Inventors: Marty L.
