Jumper settings for Shugart 810 8" floppy drive

[Dave]

Hi All,
I have a couple of Shugart 810 drives I'd like to get working with an OSI system.  While swapping the drives around, I made some changes to the jumpers, but now I can't find the notes I made of the original configuration.  Does anyone have information on the function of the various jumpers on these drives?  I found some manuals online, but they don't seem to have the jumper info.
Any information would be most welcome!
Thanks,
Dave
