Yeah, I don't think that the FDHD manual would have retained that name once the drive itself was re-branded. At a minimum, the name FDHD would have been replaced throughout the manual. Otherwise, I don't think there would have been any difference in the mechanism, or operation of the drive. Perhaps they switched from the auto-inject variety to the cheaper manual inject, but that would be about it. Maybe more details about using it with the Apple II? I'll have to look at my FDHD manual and see just how much it talks about the Apple II, for which it was almost exclusively marketed after the SE line was canned, and as you point out most, if not all Macs came with a hard drive. And only a few Macs retained an external floppy disk connector, most likely (particularly in the case of new Mac IIs) for backwards compatibility with 800K externals, and any external FDHD drives someone might have previously purchased. I would venture to say that if someone who bought the Mac Classic for $999 with a single disk drive, most likely opted to upgrade to a hard drive, either at purchase, or when the single drive wasn't enough, considering the relative cost of the ext SuperDrive. Let's face it the $999 configuration was strictly for marketing purposes only.
