Long story short...

Prior to Compro's origin, System Engineering Laboratories (SEL) was established in 1961, providing high-performance 32-bit minicomputer systems used in mission-critical, real-time applications. In 1980, Gould Electronics acquired SEL, becoming their Computer Systems Division (Gould CSD). Independently, Encore Computer Corporation was formed in 1983, creating massively scalable systems using open systems, merchant microprocessors and parallel technologies. In 1988 Nippon Mining purchased most Gould assets, while Encore purchased Gould CSD. In 1998 Gores Technology Group acquired Encore Computer Corporation, and renamed it Encore Real Time Computing.


COMPRO begun separately in 1985 founded by Douglas and Constance Beck, and initially providing comprehensive multi-vendor logistics and support services (including SEL/Gould/Encore) to computer and flight simulation sectors world-wide.


In 2002, COMPRO completed an asset purchase of Encore Real Time Computing, including its accompanying legacy SEL/Gould resources, technology and expertise.


Today, COMPRO Computer Services, Inc. (dba: COMPRO) is an international supplier to flight simulation, data acquisition, transportation and energy markets, including original equipment manufacturers and integrators (Boeing, Lockheed, Thales, EADS, among others) serving those markets. COMPRO develops interfaces and integrates commercial-off-the-shelf (COTS) hardware and software demanded by today’s most challenging real time applications. COMPRO continues the tradition of long-term product support by offering replacement solutions (e.g., the Legacy Computer Replacement System, or LCRS) that emphasize backward-compatibility coupled with future-proofing. Our Real Time Environment (RTE) is the world's fastest, most deterministic, lowest-latency real time computing solution available. COMPRO’s Technology Obsolescence Protection (TOP) and Guaranteed Long-Term Support (GLTS) services assure that COTS solutions remain viable throughout decades-long program life cycles.

COMPRO headquarters is an ISO 9001:2015 Registered Company.


COMPRO is known worldwide for its customer-focused leadership in technology, support solutions and innovative "industry-firsts.". Since its founding in 1985, COMPRO has grown from a small service company specializing in personal computer products and advanced networking to a world-wide market leader in real time products, simulation, and services. To better serve customers and leverage resources, Compro is organized into three major groups:

The Real Time Products Group provides highly deterministic, low-latency systems and software tools required by the world’s most demanding markets, including aerospace simulation, engineering simulation, development, range systems, telemetry processing, energy, transportation, process control, and interactive multimedia server markets.

The Simulation Solutions Group delivers turn-key flight simulation devices and computer-based trainers. They also provide life cycle upgrades and modifications to military and commercial legacy training systems. COMPRO entered the training systems market by developing a unique specialty: modifying previously-built simulators. COMPRO has expanded its capabilities, spanning a full range of services including simulator systems and instrument integration, cockpit overhaul, modernization, refurbishment, and hardware/software upgrades.

COMPRO's Comprehensive Services Group offers customer-centric, total-system service and support, delivering programs accommodating individualized computing environments. These services ensure program success at any support-level requirement. COMPRO continues support for SEL, Gould and Encore SelBUS-based computer systems as the world's only authorized and qualified service provider.
