Sounds right.  I couldn't find the doc you mentioned -- the ones I
checked on bitsavers don't show the frequencies, but they do show that
you get your choice of four "speed groups" according to the crystal
you pick.

Anyway, Jameco or Digikey may work, if the frequency you need happens
to be a stock one.  If not, contact a crystal manufacturer.  In years
past, I've ordered crystals for a custom frequency, quantity one,
completely painlessly from International Crystal.  It seems odd, but
they have no trouble with custom orders for just a single part.
