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 [[#mec_3v0|MEC 3v0]] control board and the Mitsumi 69-3147 motor board. ===== Pictures ===== | {{:5_25_floppy_drives:mitsumi_newtronics_d509v3:back.jpg?200 |}} | {{:5_25_floppy_drives:mitsumi_newtronics_d509v3:top1.jpg?200 |}} {{:5_25_floppy_drives:mitsumi_newtronics_d509v3:top2.jpg?200 |}} | {{:5_25_floppy_drives:mitsumi_newtronics_d509v3:bottom.jpg?200 |}} | | {{:5_25_floppy_drives:mitsumi_newtronics_d509v3:front1.jpg?200 |}} \\ {{:5_25_floppy_drives:mitsumi_newtronics_d509v3:front2.jpg?200 |}} | ::: | ::: | | {{:5_25_floppy_drives:mitsumi_newtronics_d509v3:pcb.jpg?200 |}} | ::: | {{:5_25_floppy_drives:mitsumi_newtronics_d509v3:label1.jpg?200 |}} \\ {{:5_25_floppy_drives:mitsumi_newtronics_d509v3:label2.jpg?200 |}} | ===== Jumper settings ===== ==== MEC 3V0 ==== {{ :5_25_floppy_drives:mitsumi_newtronics_d509v3:mec_3v0.pdf |}} ++++View PDF| {{pdfjs 100%,800px>:5_25_floppy_drives:mitsumi_newtronics_d509v3:mec_3v0.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.
