Yep, I bet you're all right:  Digikey probably got me.

The funny thing is, though, that I did order online.  And the invoice
indicates a 20.000 MHz crystal, as does the printed label on the
static-proof baggie in which the crystal came.  Must have been a stocking
error.

Not that I'm complaining; I've ordered plenty of times from Digikey, and
this is the first glitch.  I'll deal with the 18.4 MHz crystal, I suppose,
since it works just fine....  No point in making them spend a few bucks to
ship such a tiny thing.  :-)

Thanks to all,
Jake
