[Coco] Jumper settings needed

[LinuxRules]

Looking for some help with jumper settings.....

I am in the process of setting up a Win98se box for running
Coco emulator and Xching files. Works OK for transfer
using 720K media with the built-in floppy, but I want
360K (5") also.

So I added a Mitsubishi M4853 (not the dash 1). Neither
DOS or Win see the drive! After beating my head against
the wall for a bit, I found that DOS claims the drive is
"Not Ready". (Win silently fails - OF COURSE).
Hmmmmm.   Jumper change needed!

None of the many jumpers seem to have labels that relate
to RDY, READY, on anything similar .  Several hours
of Google produced nothing of value So,  I am asking
the group if anyone has a listing of the jumper settings
for this drive..? Or a URL  to  a page with the settings????
A URL to the manual for the drive???   Anything with
the jumpers would be helpful.

Really not wanting to trace the schematic of the PCB!!

thank you,
