Actually all 9133V and 9133XV should have the same controller (09133-69508)
at least that's what the book says:

	http://bitsavers.org/pdf/hp/disc/09134-90032-Aug-1983.pdf
	page III-1-2 (9133V/XV & 9134XV Theory of Operation).

Regarding the jumper settings for selecting between 4 volume (HP-85
compatible) vs 1 volume configurations, Section II of the manual which
refers to the 9133A/B, 9134A/B and the 9135 drives, shows the J6 jumper
settings on page II-1-9 [1], while Section III has a table on page III-1-1.

BTW this manual provides a wealth of information about all the Amigo
compatible members of the 913X family.  It is beautifully scanned in B&W
(pictures in greyscale) and produces high-quality printed output.

If you have an early version 913X, this manual is a must-have.

[1] early versions of the 9133A, 9134A and 9135A drives used a different
controller which does not appear to be configurable (see page II-1-2).
