====== Epson SD-700 ======

⚠️ This drive is frequently packaged as an SD-880 with a SD-800 3.5" floppy piggybacked on top. In this case, you //must// physically disconnect the 3.5" flex cable before using it with the Applesauce!

===== Jumper Settings =====

There are two jumpers that are of interest, marked in areas **SS1** and **SS2**.  SS1 determines which of the two drives will be seen as "A" drive.  SS2 Jumper L controls the Logic of the 5.25" drive's motor, flipping whether low or high logic puts the drive into Double-Density mode or High-Density mode, which the documentation refers to as NORM and HIGH modes, respectively. SS2 Jumper D controls the 5.25" motor speed when in NORM mode.  This jumper comes factory-configured to be 360RPM, but Applesauce expects the lower 300RPM for DD disks and the higher 360RPM for HD disks.
