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.
We presently offer the following STD Bus products to serve the embedded control marketplace:
MSI-C432 - Analog Input Card
