Since the announcement of VMEbus in 1981 there have been a great number of people and ideas that have had an impact on the development and advancement of open standards used in critical embedded computing systems. The intention of the VITA Technologies Hall of Fame is to honor and preserve the remembrance of those people and technologies that have had the greatest influence on the VITA open standards industry. Many others are to come – innovators and influencers who have made a significant impact on developing, designing, creating the technology, and ferrying the technical specifications into open standards. These are the people who have overcome the technical and procedural problems, the products that set new expectations. It is our pleasure to honor these primary contributors to this industry.

On November 20, 2013, VITA Technologies announced its first inductee into the VITA Technologies Hall of Fame. Many more inductees are slated to be brought into the VITA Technologies Hall of Fame each year.

Recently Inducted


Lyman Hevle

Lyman Hevle was the founding executive director of the VMEbus International Trade Association (VITA). He held that role from its inception in 1984 until 1993. During his career Lym was focused on the business and market growth of VMEbus. He passed away in January 2016, and his legacy will live on in the industry. Lym's own words best describe his involvement with VMEbus and how he came to be the founding executive director of VITA. The following discourse is an excerpt from his autobiography.

2eSST – ANSI/VITA 1.5-2003 (R2009)

This specification is an extension of the ANSI/VITA 1-1994, VME64, and ANSI/VITA 1.1-1997, VME64x specifications. It defines a transfer protocol based upon source-synchronous concepts that permits the VMEbus to operate at rates to at least 320 MBps. As technology improves, this rate can be extended to higher levels. The 2eSST specification emerged out of the MBLT and 2eVME concepts that extended the performance of VMEbus data transfers. Figure 2 compares the VME64 and 2eSST standards. Thales Computers designed the Alma2e bridge supporting the 2eSST protocol in 2002. Tundra Semiconductor, working with Motorola, brought the Tsi148 PCI/X-to-VME2eSST bridge to market in 2004, making the 2eSST protocol available to the entire industry. Concepts exist to enhance VME2eSST…

VMEbus started on its path to significant performance improvements while still remaining backwards compatible with legacy systems with the introduction of the VME64 concept. In 1989, John Peters of Performance Technologies developed the initial concept of VME64: multiplexing address and data lines (A64/D64) on the VMEbus. The concept was demonstrated the same year and submitted to the VITA Technical Committee in 1990 as a performance enhancement to the VMEbus specification.

PCI Mezzanine Cards

In the mid-1990s the embedded computing industry became entrenched in a heated debate over mezzanine card standards for 3U and 6U boards. At one point, 22 different proposals were on the table, not to mention at least as many more proprietary options. S-bus, advocated by Sun Microsystems, was gaining traction.  That all changed when a handful of industry-leading companies placed their bet on the emerging efforts led by Force Computers and Digital Equipment Corporation to marry S-bus mechanicals with the PCI bus. In 1994 a number of companies joined together to launch the “We Agree … It’s PMC!” campaign, including Concurrent Technologies, Digital Equipment Corporation, Force Computers, Heurikon, Intel, Interphase, Mercury Computer Systems, Molex, Motorola…

Tom Hall

Tom Hall spent numerous years in the VMEbus COTS industry selling and marketing military-spec VMEbus computer products to leading defense contractors and government departments throughout the world. He was a leading force in the development of technologies and major market segments while working at Plessey Microsystems, Radstone Technology, PEP Modular Computers, and Thales Computers.  Tom was responsible for the operation and major sales of Radstone Technology’s military products division. He also was president and CEO of PEP Modular Computers in Pittsburgh, where he was responsible for restructuring the German-based company’s U.S. operation. Tom later became the president and CEO of Thales Computers in Raleigh, North Carolina, a supplier of PowerPC and Pentium-based VME computing hardware,…

Eike Waltz

Eike Waltz was a familiar face at VITA Technical Committee meetings in the early days. He was passionate about the mechanical aspects of VMEbus and served as the driving influence in many of the decisions made to guide the development of the mechanical specifications for VMEbus. Eike received special recognition for his extensive contribution to the mechanical chapter (Chapter 7), which was incorporated into Revision C, ANSI/IEEE Std 1014-1987, and ANSI/VITA 1-1994 (S2011). Eike was a technical sales manager at Schroff, an English company headquartered in Warwick, Rhode Island. He was a representative of the British Standards Institute committee on IEC 48D from 1976 to 1983. He also was a member of the IEEE P1014…

Kim Clohessy

Kim Clohessy was a founding vice president of Dy 4 Systems in Ottawa, where he was recruited from Bell Northern Research. Dy 4 Systems, which was formed in 1979, specialized in the design and manufacture of high-end VMEbus open architecture computer systems for the aerospace and defense industry. Kim helped Dy 4 Systems grow successfully before leaving in 1992 to move to Scottsdale, Arizona, as a consultant for Ottawa-based Object Technologies and as vice president of Embedded Systems at IBM. In 2000 he transferred to Perth, Australia, where he soon resigned from IBM to form a new company. During the early 1990s, Kim did much of the heavy lifting in terms of editing the work…

Shlomo Pri-Tal

Shlomo Pri-Tal joined Motorola in 1980, and was an originator of the VMEbus architecture. In 1984 Shlomo assumed the chair of the VME Subsystem Bus (VSB) 1096 committee. One year later, he would do the same with the IEEE 1014 VMEbus working group. Shlomo was elected chairman of the VITA Technical Committee in 1987.
