Bill holds twenty– two patents for microprocessors, microprocessor peripheral devices and microprocessor systems, and was recognized in both 1991 and 1996 at the Microprocessor Forum as a pioneer in the microprocessor industry. Mr. Mensch’s patents were used on Motorola’s original NMOS 6800 microprocessor and MOS Technology’s NMOS 6502 microprocessor families. The 6502 technology has been credited with creating the PC and video game industries. It was first used in the Commodore PET personal computer; Vic 20 consumer computer; Commodore 64 consumer computer (6510); Acorn personal computer; Apple I personal computer; Apple II personal computer; Atari video game system (6507) and personal computer (6502); and Nintendo video game system. The 6502 microprocessor is featured in a display in the Smithsonian Museum of Science and Technology in Washington DC.

Mr. Mensch’s solely– owned patents are implemented in The Western Design Center’s proprietary CMOS 65xx Microprocessor family of chips and related systems. This technology is used today in an ever growing variety of products including medical life support, automotive, industrial, consumer and personal computers. The foundation for this widespread use of the technology began when two of WDC’s 65xx Microprocessor family members were used in the introduction of groundbreaking PC and video game products. The W65C02S 8–bit microprocessor was first used in the Apple IIc personal computer and the Apple IIe personal computer. The W65C816S 16–bit microprocessor was first used in the Apple IIgs personal computer and Super Nintendo video game system.

In the fall of 1996, Mr. Mensch was honored for his outstanding contribution to the information technology industry at a ceremony during which the 6502 was recognized at COMDEX as the first of seven “defining” products in the twenty–five year history of the microprocessor. He has become recognized as the person most responsible for the continued success and proliferation of use of the 65xx technology which has been enhanced and expanded with the development of the WDC 65xx Microprocessor family products.

Mr. Mensch was born in 1945 and grew up on a dairy farm in Bucks County, PA. He attended Pennridge High School in Perkasie, PA, and graduated in 1963. He graduated from Temple University (AEET 1966) in Philadelphia, PA, attendedVillanova (Spring/Summer 1968 & Spring 1969), graduated from the University of Arizona with High Distinction (BSEE 1971) in Tucson, AZ, and then attended Arizona State University graduate courses (1971–79).

Mr. Mensch was employed at Philco Ford in Blue Bell, PA (1967–69), Motorola in Mesa, AZ (1971–74), MOS Technology in Norristown, PA (1974–77), and Integrated Circuit Engineering (ICE) in Scottsdale, AZ (1977–78), before founding The Western Design Center, Inc. in Mesa, AZ (1978–present).

From 1985 to 1988, Mr. Mensch was a member of the Board of Directors for Mesa Bank, a local community bank. Mr. Mensch was also a member of the Board of Directors for TouchScape (1999–2001) and DotSafe (2000–2001), two Internet companies.

In 1997, he was the keynote speaker at the world’s first IP (Intellectual Property) conference, IP Europe. He participated on a special panel discussion session concerning “Starting Up Companies to Commercialize University– Generated Technologies” at the ICEE– 2000 conference in Taiwan in August, 2000, which was attended by approximately 500 professors from all over the world.

While attending the University of Arizona, he was awarded a scholarship by the Tucson Gas and Electric Company. In 1985, he received the Certificate of Honor from Temple University’s College of Engineering and Architecture and has been recognized at both Temple University and the University of Arizona as an outstanding alumnus. In 1994, Mr. Mensch was named to the College of Engineering Advisory Council at the University of Notre Dame. In 1995, he was appointed to the Industrial Advisory Board for the Electronic Computer Technology Department in the College of Engineering and Applied Science at Arizona State University . In 1996, he joined the Industrial Advisory Board for the newly created Center for Low Power Electronics (CLPE), of which WDC is a charter member. In 1999, in conjunction with the CLPE, the National Science Foundation (NSF) provided an SBIR grant to WDC and the University of Arizona for development of a low power mixed signal rapid prototype system designed around the 65xx technology. From 1994– to 2000, Mr. Mensch assisted in teaching a class in System–On–a–Chip (SOC) IC Design at Arizona State University. He was chosen to receive the Distinguished Alumni Leadership Award from Temple University in April 1998. In August of 1998, he received the Sigma Pi International Fraternity’s Founders’ Award its highest individual award.
