Yes, I'd heard that, too.  :)

I've already got one, and it's a dandy.  I run the BusLogic BT-958
PCI to Wide Ultra SCIS bus master host adapter.  But I'm considering
adding some, power to this P5-120 of mine, and I'm wondering
if I can expect the BusLogic to work at the higher speeds.

True enough about the corrupted data or instability.  I couldn't agree
more.  But waiting for the 100 mhz bus mobo's may involve both quite
a wait and quite a bit of additional cost, yes?
