- The Intel 8086 microprocessor (1978) revolutionized computing by founding the x86 architecture that continues to this day. One of the lesser-known features of the 8086 is the “hold” functionality, which allows an external device to temporarily take control of the system’s bus. This feature was most important for supporting the 8087 math coprocessor chip, which was an option on the IBM PC; the 8087 used the bus hold so it could interact with the system without conflicting with the 8086 processor.
