Abstract
A modular computer system includes a plurality of circuit modules, each of which includes one or more components that are subject to failure, such as a vacuum tube. A carrier assembly is added to each circuit module of the modular computer system. The carrier assembly hosts monitoring circuitry that indicates the proper functioning of one or more components on the attached module. In one implementation, each module includes a vacuum tube, and a coil located on the carrier assembly is connected in series with the heater of the vacuum tube. A Hall effect sensor is positioned near the coil. If the heater of the vacuum tube fails, the flow of current through the coil is interrupted and is detected by the Hall effect sensor. The Hall effect sensor is connected to an LED that indicates failure of the vacuum tube.
