I have an Apple II 3.5" Disk Controller Card for the Apple II series in like new condition. The box is open, but the contents are like new. The card is still sealed in the anti-static bag and the manuals and all the paperwork is there. It even includes the wrench kit and jackpost screws, still in their sealed bags.
This card works with the UniDisk 3.5, Apple 3.5 Drive and Apple SuperDrive.
This is the only Apple 3.5" controller card to support high density floppy drives on the Apple II.
Asking $80, shipped, CONUS.
