Most drives (hard and floppy) sold through clone dealers don't come with
documentation.  I wrote Toshiba America, and a copy of the installation manual
was sent to me.  Here are the jumper locations for Toshiba MK-134FA:

Place the drive so that the jumpers-side is up and the faceplate is toward you.
From left to right:  #=installed at factory

	in=write protected, out=not write protected
	in=radial mode, out=daisy-chain mode
	in=drive select 4
	in=drive select 3
	in=drive select 2
	in=drive select 1 #
	terminator #
	terminator #
	terminator #
	terminator #
	terminator #
	terminator #

I have been running two of these drives with both sets of terminators on, since
I didn't know their locations before -- no problems so far.  Only one set of
terminators should be left in at the end of the cable.
