I'm a longtime Apple II user so not totally clueless but definitely not as technically adept as some. I've recently started trying to get a IIc Plus that I've had lying around working again; for as long as I'd had it, it just wouldn't boot. I replaced the ROM chip and now it boots and works fine, except the internal floppy drive doesn't eject via the eject button. The drive otherwise works great; just doesn't eject.
This is an 800K drive, a Sony MP-F51W-03. I've read a lot about these the past few days and have tested the eject switch (with a multimeter), the disk sensor switch, and also checked the eject motor gears. I did notice when I removed it that the eject motor seemed slightly misaligned (I understand it's supposed to be at the 12 oclock position) so I lifted one gear, turned the motor slightly and it turned easily. Then I put the gear back and reinstalled the motor. All seems fine. The drive itself looks great, almost like it was never used. There's no dirt or gunk anywhere and everything moves easily. The drive snaps the disk away quickly when loading and clamps down right away.
There are no sounds at all from the eject motor when I press the button. It's like it's not even trying. The one thing I don't really know how to test is the motor itself; I don't think I have a way to add power to it by itself to see if it works. Or is there some other way to force it to eject? Some way to short it or something?
At the moment I'm suspecting the motor is just dead because I feel like I've ruled everything else out, but I don't know how to rule the motor in or out. Or is there anything else I'm missing?
I can use the computer as is by just using the manual eject pinhole, or by using my Floppy Emu. But I'd just love to get this uncommon Apple II back up and running 100%. I feel so close, but just can't figure out this one thing.
Thanks for any help!
P.S. I'm definitely open to just replacing the motor or drive if anyone wants to part with one; they're not all that easy to find.
