An input/output controller provides a numer of adjustable timers for timing events such as for polling external devices and includes circuitry which generates interrupt vector signals upon the occurrence of certain events, including the expiration of time set in the adjustable timers and also upon receipt of signals from the external devices. The interrupt signals may be selectively masked when it is not desirable or practical for an interrupt to occur. The controller is an MOS N-channel device on a single chip and is packaged in a 40 pin package and is compatible with a Model TMS 8080 Microprocessor Unit.
