Original Yamaha Service Manual for the QX5FD MIDI Disk Sequencer, QX5 FD.

This is a large, original Yamaha service manual for the Yamaha QX5FD MIDI Sequencer / Floppy drive MIDI storage Unit. I have 2 of these available, in very good, lightly used condition. It would be very helpful to work on / test / fix your QX!
