I have Chinon FX357 (rev. A) floppy drives and no manual for them.
They have worked fine as DD drives but I have run into complications
while configuring them for HD operation. I traced the PCB enough to
get disk-change working alright and find the 'ready' signal. However,
I am rather lost sorting out the HD-mode signal. There seem to be so
many options to choose from.

Does anyone have the manual and can tell me the exact funtion of jumpers
J5,J6,J7,J9,J10,J14,J15,J16,J17,J18,R55? Also I need to know the values of
R4,R5 and when they need to be fitted.

Any help appreciated,
