 Re: Random for Real

On other forums, someone pointed out this (he added he heard about that from Dave Haynie):
"Commodore tried to make "more random" numbers on the 264 series of computers (C16, C116 and plus/4) by adding a funny feature to the TED chip: There's kind of an antenna around the chip die, which picks up the radio waves generated by the chip itself, and that feeds a register that can be read by the CPU. However, I'd also say that it's not truly random, because it will heavily depend on the displayed gfx and the code that's currently executed. It'll be fuzzy, but surely not random, because there are reproducable dependencies - again, not suitable as a random seed for a cryprographic algorithm."
Ok, which's the antenna register?
