MMX was introduced on the Pentium. There was Pentium, then came
Pentium-MMX. It took a while, so Pentium Pro might have been there
before Pentium-MMX. My guess is that Pentium Pro did not have MMX.
SSE came in Pentium III.

The Pentiums are tricky with MMX, because the same board will run
just fine with Pentium and Pentium-MMX alike. So for Pentium boards
it's not really safe to assume there will ever be MMX.
The later models were slot 1 or socket 370. Could you put a standard
Pentium in a socket 370? I doubt it. Then it's safe to set MMX based
What about Pentium III? IIRC you could put an FCPGA Pentium III in an
adapter that made it into a slot 1, and could run instead of a
Pentium II.. Can't rely on the socket there.
