Programmable Keyboard/Display Interface

The Intel 8279 is a general purpose programmable keyboard and display I/O interface device

designed for use with Intel microprocessors. The keyboard portion can provide a scanned interface to

a 64-contact key matrix. The keyboard portion will also interface to an array of sensors or a strobed

interface keyboard, such as the hall effect and ferrite variety. Key depressions can be 2-key lockout

or N-key rollover. Keyboard entries are debounced and strobed in an 8-character FIFO. If more than

8 characters are entered, overrun status is set. Key entries set the interrupt output line to the CPU.
