ABSTRACT:
A digital computer system includes a central processor unit (CPU) and an optional co-processor unit, both connected to a local bus. The co-processor unit, when installed, fits into a socket having pins, the pins being connected to communicate with the CPU through the local bus. A presence-detect circuit is connected to the local bus and receives a signal indicating the presence of the co-processor unit in the socket. Logic circuitry receives the output signal from the presence-detect circuit and provides a READY-- signal in either the presence or absence of the co-processor unit.
