The wind goeth toward the south, and turneth about unto the north; it whirleth about continually, and the wind returneth again according to his circuits.
Ecclesiastes 1:6 KJV
New International Version
The wind blows to the south and turns to the north; round and round it goes, ever returning on its course.
Ecclesiastes 1:6 NIV
- Undocumented 8086 instructions, explained by the microcode (righto.com)
What happens if you give the Intel 8086 processor an instruction that doesn’t exist? A modern microprocessor (80186 and later) will generate an exception, indicating that an illegal instruction was executed. However, early microprocessors didn’t include the circuitry to detect illegal instructions, since the chips didn’t have transistors to spare. Instead these processors would do something, but the results weren’t specified.
