About Microcomputer Systems, Inc.

Microcomputer Systems, Inc., located in Baton Rouge, LA, was established in 1976 for the design and fabrication of state-of-the-art industrial instrumentation systems. The personnel of our company are highly trained individuals who specialize in hardware and software design, and in the fabrication of microcomputer networks. Our engineering personnel are well qualified having degrees ranging from the B.S.E.E. to the Ph.D. with years of practical experience in the industrial environment. Our people have been intimately involved in board level microcomputer design since the introduction of the microprocessor into the marketplace in the early 1970's. Notable works include renovation of the scoreboard and pylon systems of the New Orleans Superdome, design and manufacture of Auto/Manual Back-up Controllers used by Exxon/Esso in their worldwide refining operations, and the Lock and Dam instrumentation for navigation control on the Red River.

Custom Designs are our Specialty

We specialize in custom board design for your specific application to minimize your product cost and to maximize your product reliability by eliminating unused hardware of general purpose cards. Our custom designs for clients range from multi-processor cards (e.g., nine MC68HC811E microcontrollers on an inter-module bus) to special I/O cards, both digital and analog. Recent developments include isolated analog input cards for the Mexican Metro system, special MODEM and Tone Decoder cards for the FAA Instrument Landing System (ILS) in commercial aviation, and a 16-channel serial multiplexer card for a major U.S. corporation.

STD Products

We presently offer the following STD Bus products to serve the embedded control marketplace:
