Article note: This is extremely cyberdeck, in the actual Idoru box with glasses and gloves (not that last part) sense that few things that use the term match up with.

Apple has an invalid instruction in the ROM of the Classic II (ca.1991), whose undocumented behavior on real hardware is necessary to compute an address during the boot process.
Discovered because emulators that implement the documented instruction set crash, either on the invalid instruction or on the next instruction because the side-effect didn't happen.
It’s my belief that history is a wheel. “Inconsistency is my very essence” -says the wheel- “Rise up on my spokes if you like, but don’t complain when you are cast back down into the depths. Good times pass away, but then so do the bad. Mutability is our tragedy, but it is also our hope. The worst of times, like the best, are always passing away”.
