- A close look at the 8086 processor’s bus hold circuitry (righto.com)
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.

Boötes (/boʊˈoʊtiːz/ boh-OH-teez) is a constellation in the northern sky, located between 0° and +60° declination, and 13 and 16 hours of right ascension on the celestial sphere. The name comes from Latin: Boōtēs, which comes from Greek: Βοώτης, translit. Boṓtēs ‘herdsman’ or ‘plowman’ (literally, ‘ox-driver’; from βοῦς boûs ‘cow’).
