Sigh, the crystal output is dead as a doornail. Total flat-line. Guess I'm
going to have to find a new one...
Does it have to be exactly 13MHz for the system to function correctly? I
have some Fox brand 13.824MHz oscillators in my parts cabinets that were
leftovers from something back in the mid 90s (probably modem R&D).
