Weren't expected too, I would have said. However, overdrives are
supported: 125, 150, 166 and 180 MHz.

I've also used the IDT/Centaur Winchip C6, in a socket-5. Still works,
too :)

Yes, there were at least two specs supported by Intel. I (and many
others) refered to them as: P54C and P55C. The P54C is single voltage,
and P55C spilt or dual voltage.

The later CPUs from the others also required a Super-Socket-7, which has
100MHz FSB, among other things.
