Provided the "crystal" is actually an integrated oscillator (with
Vcc, GND and a TTL or CMOS logic level output, that is), this should
work. (Pure crystals depend on some additional components on the
board, so you have to dig some more to insert an external clock, or to
extract a usable signal.) You may have to use coax cable and/or some
buffering to get a fine clock signal to the slave card.
(Note: Of course, the two cards have to use the same oscillator
frequency in their original shape, or you'll end up with one card
behaving very strangely... :-)
