"Termination Power" IS a real and very accurate term. SCSI termination isn't just a simple resistor, it is a voltage divider between the power rails assumed to be used by devices on the bus (I think 5v and ground like TTL). Somebody has to supply the upper power rail to the termination resistors, and that's what they mean when they talk about termination power. At least one (I forget if it is exactly one) device on the bus has got to supply termination power or else the termination resistors are going to look like a bunch of resistors to ground and a bunch of resistors to common point that is floating with no fixed voltage.
