DY-4 Systems Collection



Objects manufactured or published by DY-4 Systems Inc.


DY-4 Systems Inc. was an Ottawa-based high technology company founded by four engineers Garry Dool, Terry Black, Kim Clohessy, and Steve Richards in 1979. In the early 1980s, DY-4 designed and manufactured a variety of products including microcomputers (the ORION series), graphics terminals, and STD bus board level products (including single-board computers). In the second half of the 1980s, the company shifted its attention to the development and manufacturing of products for harsh environments. A wide range of products based on VME bus architecture was offered for applications in areas such as air traffic control, tactical command, control and communication, flight management for airborne applications, ground tactical support, process control, and robotics. The products included single-board computers, memory modules, intelligent peripheral controllers, special function modules, and I/O modules. By 1993, when DY-4 went public, the company was already a technological leader in the ruggedized embedded computing market providing open systems board-level products, support systems and related software to harsh environment systems integrators. DY-4 products found their way to new generations of tanks, submarines, airplanes and spacecraft in many countries around the world.

The company entered the 21st century retaining its premier position as embedded computing solutions provider in the defense and aerospace industries. In 2004, after a series of acquisitions, DY-4 business was bought from Solectron (Milpitas, Ca) by defense contractor Curtiss-Wright Corp. (Roseland, N.J.).

Acquisition: The objects in the collection have been donated or acquired from: Dave Dunfield, Mati Sauks, and Zbigniew Stachniak.
