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. ===== Pictures ===== | {{:5_25_floppy_drives:mitsumi_newtronics_d509v2:back.jpg?200 |}} | {{:5_25_floppy_drives:mitsumi_newtronics_d509v2:top1.jpg?200 |}} {{:5_25_floppy_drives:mitsumi_newtronics_d509v2:top2.jpg?200 |}} | {{:5_25_floppy_drives:mitsumi_newtronics_d509v2:bottom1.jpg?200 |}} {{:5_25_floppy_drives:mitsumi_newtronics_d509v2:bottom2.jpg?200 |}} {{:5_25_floppy_drives:mitsumi_newtronics_d509v2:bottom3.jpg?200 |}} | | {{:5_25_floppy_drives:mitsumi_newtronics_d509v2:front1.jpg?200 |}} \\ {{:5_25_floppy_drives:mitsumi_newtronics_d509v2:front2.jpg?200 |}} \\ {{:5_25_floppy_drives:mitsumi_newtronics_d509v2:front3.jpg?200 |}} | ::: | ::: | | {{:5_25_floppy_drives:mitsumi_newtronics_d509v2:pcb1.jpg?200 |}} {{:5_25_floppy_drives:mitsumi_newtronics_d509v2:pcb2.jpg?200 |}} | {{:5_25_floppy_drives:mitsumi_newtronics_d509v2:label.jpg?200 |}} | ::: | ===== Jumper settings ===== ==== TSD 2 "A" ==== {{ :5_25_floppy_drives:mitsumi_newtronics_d509v2:tsd_2_a.pdf |}} ++++View PDF| {{pdfjs 100%,800px>:5_25_floppy_drives:mitsumi_newtronics_d509v2:tsd_2_a.pdf?page-width}} ++++ ==== TSD 2 "B" ==== {{ :5_25_floppy_drives:mitsumi_newtronics_d509v2:tsd_2_b.pdf |}} ++++View PDF| {{pdfjs 100%,800px>:5_25_floppy_drives:mitsumi_newtronics_d509v2:tsd_2_b.pdf?page-width}} ++++ ===== 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.
