I assume this thing isn't rare and valuable or anything? I plan to use the enclosure with the Disk II Floppy Emu faceplate kit, but I figured I ought to ask around before I gut it.
It uses a Sugart 390 mechanism. Slightly different than what is in my real Disk IIs, but looks to be electrically the same. Analog board appears to be a clone of the Apple one. Case has different vent slot placement, but otherwise appears identical to Disk II.
I had the drive as my D2 from 1983 until last year sometime when I replaced it with another Disk II that a friend sent me. It's always been slightly unreliable. Sometimes it throws IO errors and you have to remove and reinsert the disk before it will work right. I suspect that the spindle speed is a little off, but I haven't tried to adjust it.
I plan to keep all the innards, as they will fit into a Disk II (and the faceplate may even swap) if one of my Disk IIs breaks down and I get in a bind, heh.
