It uses a metal belt to facilitate head movement and locks the disk with a lever. Head loading is done via mechanical linkage. It uses the [[#pn128206-01_rev_b|TPN128206-01 Rev. B]] control board and the Sankyo SB68A motor board. ===== Pictures ===== | {{:5_25_floppy_drives:ye_data_yd-380b:back1.jpg?200 |}} \\ {{:5_25_floppy_drives:ye_data_yd-380b:back2.jpg?200 |}} \\ {{:5_25_floppy_drives:ye_data_yd-380b:back3.jpg?200 |}}| {{:5_25_floppy_drives:ye_data_yd-380b:top.jpg?200 |}} | {{:5_25_floppy_drives:ye_data_yd-380b:bottom.jpg?200 |}} | | {{:5_25_floppy_drives:ye_data_yd-380b:front.jpg?200 |}} | ::: | ::: | ===== Jumper settings ===== ==== PN128206-01 Rev.

A major modification is required to enable this. {{:5_25_floppy_drives:ye_data_yd-380b:mod_84tracks_1.jpg?200|}} {{:5_25_floppy_drives:ye_data_yd-380b:mod_84tracks_2.jpg?200|}} The modification can be performed by following these steps: - Mark the current position of the stepper motor in relation to the drive body. - Unscrew the stepper motor. - Unscrew the springs that hold down the guide rod of the head assembly on the stepper motor side. - Move the head assembly and guide rod out of the way. - Use a rotary tool to grind down the head assembly end stop as pictured. - Clean the drive of any metal dust. - Put the head assembly and guide rod back in place. - Screw down the springs that hold down the guide rod of the head assembly on the stepper motor side. - Screw down the stepper motor so that it can still be moved with some friction. - Reposition the stepper motor in relation to the drive body using the marks done earlier. - Screw down the stepper motor all the way. - If the positioning isn't done right the tracks have to be re-aligned.
