== 3.5" Drive Compatibility Chart ==

There are 3 types of 3.5" drives for Apple Computers:
NOTE:Any of these drives with the exception of the UniDisk 3.5" can be used with the Laser Universal Disk controller installed in a slotted Apple II.

The FDHD/SuperDrive will function as an AppleDisk 3.5" 800K drive only, when attached to the SmartPort on the IIc Plus.

See the the section on [[Floppy Controllers]] for details on what these descriptions mean.

Apple ][ & ][+ support listed is with respect to electrical/mechanical needs. Additional software and memory is likely required. IE, AppleSoft ROM for the Apple ][, 64K system RAM and ProDOS. ProDOS 1.0 does run on 48K but you can't do much. The requirement was upped to 64K with later releases.

Some of these drives without eject buttons will require the constant use of a paper clip or software eject initiation where available. This applies to the Apple 400K, 800K and Ehman drives.

*The Teac reference can apply to most any 34 pin DSDD or DSHD MFM drive. MFM will provide 720K DD or 1.44MB HD and will NOT read 800K GCR disks. The MFM 720K volume will be a ProDOS volume. This will NOT be readable in any 800K drive either. Only the SuperDrive or AE HD 1.44 will read the 720K ProDOS volume, or any other 720K volume, period.  These can be used with the Blue Disk or Urphi controller only. 

The FDHD/SuperDrive requires a separate controller card, the Apple II 3.5" Controller Card, Apple P/N A0076LL/A in order to function as a high density drive with an Apple //e. The FDHD Drive will function as a normal 800K (AppleDisk 3.5") when connected to the Apple Universal Controller or UDC.

The SuperDrive controller itself requires an Enhanced //e to function and therefore will not work with anything less.

The FDHD/SuperDrive requires a separate controller card, the Apple II 3.5" Controller Card, Apple P/N A0076LL/A in order to be used as a High Density drive on a IIgs. The controller card will also handle 800K. The FDHD Drive will also function as a normal 800K (AppleDisk 3.5") when plugged in the back of the IIgs as opposed to being used with the controller installed. The AEHD+ will function as a 1.6MB drive when connected to the SmartPort, with the appropriate device driver installed in GS/OS.
