I remember the warning, I just didn't remember
there being different
crystals. So I dug out my Europlus, and sure enough, I misremembered.
The crystal is 14.25045MHz instead of 14.31818MHz.
Annoyingly the crystal frequency -- not even for the NTSC model -- is not
given anywhere tht I can obviosuly see in the manual. It's not in the
'Eurapple' seticon, and it's not on the schematic (neither the scheamtic
pages in the main part of the book or the fold-out one. I will add this
information to my manual.
