Internal Floppy stuck / broken gear
Apple IIC+ OH NOES! My internal floppy eject mechanism has failed. I had to remove the little motor assembly that pushes the internal eject lever, and now I push that manually when I want to remove a floppy. (I push the eject button, which is wired to the motherboard, wait a moment, then push the mechanical lever to physically eject the disk) The motor assembly has a gear that has disintegrated.
Does it use the same mechanism as Macintoshs? If so those gears are really cheap now on ebay. https://www.ebay.com/itm/235320197466
Lil noisy compared to the original. But 4 of them for the weed number you can't argue with that.
I think they are likekly to be different - the mechanism on a Mac can hold more per disk. There is a picture of a Mac drive and it looks different than the drive inside the shield of my Apple IIC+ internal drive.
Are you sure they're different? They might be similar enough honestly.
Here's a IIC + drive
And here's an 800k mac floppy.
I don't have any spare 800k drives lying around to compare. But here's more photos of a IIC+ drive.
Worst case just pop open the auto eject mechanism and take a look. It already doesn't work.
I finally unplugged the internal floppy and plugged in the BMOW floppy emu instead - it boots the system with a full up prodos image, and then I can have "guest" floppies in the external drive to store programs.
