Abstract
A computer having a plurality of plug-in modules is provided with a holding circuit for transmitting an interrupt signal over an interrupt signal line. The holding circuit conducts the interrupt signal in the appropriate manner regardless of whether or not a given module is plugged in. At the same time it ensures that a plugged-in module responds to the interrupt signal in the appropriate manner.
