I remember the many undocumented opcodes on the 6502. Back then, processor bugs were fun, not security problems. You could bitwise AND the Accumulator and X register in one instruction, instead of having to use 4 or five instructions when using the normal AND.
The ultimate hardware bug on the C64 was no doubt the discovery of hardware scrolling, used in Mayhem in Monster Land. How on earth someone found out that messing with $D011 during the IRQ could unlock a feature that was never meant to exist is beyond me.
Awww.. stop it! You're bring back ssoo many fond memories.. 6502.. beautiful piece of hardware for its time.
Accident, or perhaps secretly shared knowledge not meant for the masses?

This is the worst excuse you hear over and over in discussions whether hardware or software related.
"Yes, we acknowledge a problem, but we're better than competing product X."
Anytime you can bring awareness to possible security problems in todays environment is a good thing.

its not possible to make a perfect processor (a bug free one). Yes Core 2 arch has its bug, but lets see late August the barely finished barcelona
