Applied Electronics HD External Floppy Drive?

So I found this locally for a few bucks. I tried looking it up, but none of them have the HD logo on it. Is it the same as the high density one, just with a logo? (IE a possible revision?)

I've seen ones with just the Applied Engineering logo, and units that have "AE HD+," but not one like this with "AE HD" before.

I have this same drive - not exactly sure what it does and doesn't work with; haven't taken the time to look it up.

Putting together the pieces from various Google hits it looks like the "HD" labeled version of the drive is just an Apple Superdrive-compatible external floppy. (IE, supports 400k/800k/1.44mb on machines with SWIM controllers.) The "HD+", on the other hand, appears to be a Smartport-type device similar to the old "Unidisk" 800k drive that supports reading and writing high-density disks on machines without high-density controllers.

What Gorgonops said. The plain HD is equivalent to an (old nomenclature) Apple external Superdrive. The HD+ is a 1.44 floppy with a big ol' circuit board that makes it work with a Mac Plus or other Mac that lacks SuperDrive support. Back when all I had was q Plus I lusted after the HD+. I have one in a box here somewhere.

The manufacturer is Applied Engineering, BTW.

Sorry,  yeah...I was thinking of another thing lol. Thanks for the info guys!

Thanks all - that's what I thought, but it's nice you confirmed my suspicions. I remember the HD+ being a big deal at the time.

On the IIgs the AEHD+ with a driver let the IIgs use HD floppy disks at 1.6mb. Since I only had one of the drives I didn’t want to store data on 1.6mb disks in case the drive died. Superdrive cards on the IIgs was a better choice anyways.
