3.5" external floppy manual eject button not working
Posted by: naujoks on 2023-03-24 15:29:09
I have a A9M0106 external floppy, the manual eject button is not working, I'm using it with a Mac Plus.
According to the owner's manual it should work, though I've read somewhere it's only supposed to work with an Apple II but not a Mac - which is true?
I've checked the button, that's fine, so are the leads. Shorting the pins of the connnector also doesn't do anything.
Any other ideas what I could check?

does it make any noise when you attempt to eject, or does it just do nothing?

I don't think that button does anything when connected to a Mac. Drag the disk to the trash, that ejects it.

Phipli is correct. That is non-functional on any Mac. It only works on an Apple II.

That is so cumbersome! I mean, the button is right there!

It's the same as every Mac removable media drive - Floppy, CD, Zip etc. - from the 128k Mac right up until they dropped optical drives.

I suspect the intention was that you should never need to move your hand from the mouse. It's only convoluted if you are used to, and expect, to need to manually eject stuff.

I'm going to have a word with Woz about that.

Can be modified to suit.

How!

Remember: it was a safety mechanism. You can’t eject the disk until the machine is done with it. Makes far more sense than manual ejects. It’s the same with CD/DVD drives on the Mac: can’t eject with a button unless the OS sends the signal to eject.

Not an easy mod, the eject motor loom should be modified.

ah nvm then
It's going up for sale. I need to raise funds for a floppy emu which costs $$$$$$$.

Some time ago I had one connected to an Apple II UDC card which didn't allow the eject button to work. Using a paper clip got old really fast.
So I unplugged the eject button wire from the circuit board and connected it to a couple of thin wires, One wire went to power and the other to the eject motor.
I'm not using the UDC card now so I returned the drive to original
