On 5.25" drives (i.e., FD-55GFR and pals), there
are straps to control when
to light the LED and when to fire up the motor. I cannot figure out if there
is a way to tell this floppy to spin based on other signals than MOTOR ON.
Do motor on ON DRIVE SELECT.
I've found not less than 6 different boards in FD55GFR series, frustrating
as it's a really good drive.
