Manual for IDE Syquest EZ135

"Googling turns up a manual for some of their DOS utilities which explains:

This software is designed to support SyQuest IDE drives connected to a generic IDE adapter, a SyQuest SQ08 IDE controller, SyQuest EZ135 PP
drives and SyQuest EZFlyer PP drives
...

At the end of this file, there is a short description of the jumpers
on the SyQuest internal IDE drive.

So it sounds like this would apply to an IDE EX135. At the end:

Master/Slave jumper pins

This set of jumper pins is on one end of the jumper block and
is marked as such. The drive is a master when a jumper is
installed on the pins, slave otherwise.

You can connect one or two IDE drives to an IDE cable.
If you have only one drive, it must be Master, if you have
two, one must be master and the other must be slave.

System uses the master drive first. If you already have
an IDE drive on the system, you need to find out how to
configure it so that it will work with a slave SyQuest
Drive.

All other sets must not be jumped.

Sounds pretty standard. Does this match what you see on the drive?"
