The Word: No more than two. One is OK if there are only two devices and
a single short cable, but two are always better. Terminators should always
be AT the end of the chain if at all possible.

The High Speed SCSI does in fact have termination built in to the card. You
can see it in the form of three thin yellow things (9 pins each) sticking
up next to where the cable is soldered to the card (argh, should have been
socketed).
