Abstract
The disclosure describes improved apparatus and method for implementing the test of various computer functional units interconnected by a common bus. At the beginning of the method, each functional unit is subjected to an enforced condition which disconnects it from the bus. Then, one of the units is subjected to an enforced condition which connects it to the bus and is tested under microprogram control. After the one unit has been tested, another unit is connected to the bus and is tested. In this manner the functional units after first being disconnected from the common bus are reconnected and tested one at a time and those units which have no error detected therein are maintained connected.
