You're right; Maurice said the same thing.  They buy the 14 MHz part, check
it out to make sure it works to 20 MHz and just start using it.  He also
told me that it is rare to get a 65816-14 that can't be clocked to 20 MHz,
but that they usually become unstable by 22 MHz.

Even so, a IIgs running at 20 MHz sounds pretty cool to me.
