SCSI Terminator Select
The SCSI terminator select register is a one-bit (SD15) write only register
located at ISA I/O address x0950. If a one is written to this register, the
SCSI terminator is disabled. If a zero is written to this register, the
terminator is enabled (assuming the on-board jumper described below is
not installed). This register is cleared by a hard reset (terminators are
enabled). This register may be overriden by installation of an on-board
jumper at J36. The jumper disables the on-board SCSI terminator,
regardless of the state of the terminator select register.
