- Here be dragons: Preventing static damage, latchup, and metastability in the 386 (righto.com)
I’ve been reverse-engineering the Intel 386 processor (from 1985), and I’ve come across some interesting circuits for the chip’s input/output (I/O) pins. Since these pins communicate with the outside world, they face special dangers: static electricity and latchup can destroy the chip, while metastability can cause serious malfunctions. These I/O circuits are completely different from the logic circuits in the 386, and I’ve come across a previously-undescribed flip-flop circuit, so I’m venturing into uncharted territory. In this article, I take a close look at how the I/O circuitry protects the 386 from the “dragons” that can destroy it.

William Marrion Branham (April 6, 1909 – December 24, 1965) was an American Christian minister and faith healer who initiated the post-World War II healing revival, and claimed to be a prophet with the anointing of Elijah, who had come to prelude Christ’s second coming; some of his followers have been labeled a “doomsday cult”. He is credited as “a principal architect of restorationist thought” for charismatics by some Christian historians, and has been called the “leading individual in the Second Wave of Pentecostalism.” He made a lasting influence on televangelism and the modern charismatic movement, and his “stage presence remains a legend unparalleled in the history of the Charismatic movement”.
