  PPros are quite hard to find now because the "gold scavengers" loved them. As i recall, at the peak in 2008, they were $100ea and more for the ceramic packages. All that interconnect was tiny gold wires, apparently.

    Heh, had no idea, they seemed to have a pretty limited run, ran at up 200 MHz, but was pretty quickly replaced by a Pentium-II at 233 Mhz on a single die.
