Drive supplies power to I/O pin 26 of SCSI
bus; none to internal terminators. When
drives have differential I/O circuits a jumper
on the right TP position may be needed to
power external terminator (see system docu-
mentation). The "WD" drive has differential
I/O circuits which have no terminator circuits
on the drive. The "WC/DC" Model drives
have no provisions for terminators on the
drive and no provisions for terminator power
on the 80 pin I/O connector.
