- 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.

Spaceballs is a 1987 American space opera parody film co-written, produced and directed by Mel Brooks. It primarily parodies the original Star Wars trilogy, but also of other popular franchises such as Star Trek, Alien, The Wizard of Oz, 2001: A Space Odyssey, Planet of the Apes, and Transformers. The film stars Bill Pullman, John Candy, and Rick Moranis, with the supporting cast including Daphne Zuniga, Dick Van Patten, George Wyner, Lorene Yarnell, and the voice of Joan Rivers. In addition to Brooks playing a dual role, the film also features Brooks regulars Dom DeLuise and Rudy De Luca in cameo appearances.
