-====== Mitsumi D509V2 ======
+====== Mitsumi/Newtronics D509V2 ======
+The D509V2 is a 5.25" double sided high density floppy drive made by Mitsumi and Newtronics.
+It uses a leadscrew to facilitate head movement and locks the disk with a lever. Head loading is done with via mechanical linkage.
+It uses the [[#tsd_2_a|TSD 2 "A"]] (83 maximum seek-able tracks) or [[#tsd_2_b|TSD 2 "B"]] control board and the Kumagaya 771N1 or Mitsumi M90BCL-3  motor board.

+===== Common issues =====
+==== Broken solder joints on power connector ====
+The solder joints of the power connector can break over time and after repeated plugging and unplugging.
+\\ {{:5_25_floppy_drives:mitsumi_newtronics_d509v3:fix_powerconnector_1.jpg?200|}} \\
+This causes problem with power delivery to the drive resulting in abnormal behaviour.
+\\ {{:5_25_floppy_drives:mitsumi_newtronics_d509v3:fix_powerconnector_2.jpg?200|}} \\
+To fix this issue the solder joint have to be simply re-soldered.
