Teklogix
Teklogix (more fully, Teklogix International Inc.) was created in 1967 by Lawrence Cragg together with a small group of engineers.The company focused on mini computer applications. It designed and built complete systems based upon DEC's PDP-8 computer, DEC's logic modules and purpose built logic. Many of the company's projects involved control of material handling systems and this led to the development of radio linked terminals for installation on fork lift trucks complete with multiplexers to interface to a variety of main frame computer systems.
In September 2000 Teklogix was acquired by U.K.-based Psion PLC, and became Psion Teklogix Inc.
