I've seen 4mc/s crystals on old IBM compatible MBs...

Yes...it can even mulitiply.

Probably. It's a Pentium 4, whatever that works out to be. 4GHz?

Me too, but I don't go around telling everybody about it. 8^)

When I was in junior high school, I was best friends with a LID who turned
me on to radio. He lived over a teen hangout (soda fountain) and had a
long wire antenna that stretched over the flat roofs of two buildings.
Together, we pioneered the new band the FCC made for CB on 11 meters in
1958-59...along came a sunspot cycle that created a lot of skip and CB was
never the same after that. Finally got a Novice ticket in 1970-71...
