Yes, I know that will NOT give me 1.558 Mhz but 1.5 Mhz but heck, for $1 for the resonator plus .39 for the flip flop, it is worth a try. From my superficial reading of the hardware description, it sounded like the mac was being externally clocked by my chosen frequency, so it (hopefully) won't matter if I'm ~3% low. Flames to /dev/null, but constructive criticism/feedback to comp.sys.mac.hardware ******************************************************************* Alan R.
