This article describes a personal computer which is ruggedized for use on a plant floor. A fan is used to obtain positive pressurization to reduce particulate contamination. A cable retainer prevents power cables and the keyboard cable from being accidentally removed. A retaining bracket is used to maintain the logic cards in position in the computer. The present disclosure sets forth several modifications to the IBM Personal Computer XT so that it can function in a class "C" industrial environment as well as environments with moderate particulate contamination. Figs. 1 and 2 show the two basic configurations of the industrial computer. Fig. 1 shows a system with a single 5 1/4 inch diskette and a 10-megabyte hard file. Fig. 2 shows the second system consisting of two 5 1/4 inch diskettes.
