- It's actually an 800K drive (on a Mac, anyway).

- My old copy of "The Macintosh Bible" says that the Unidisk was intended
- for the Apple II, but can be used as an external Mac 800K drive by
- bypassing the internal disk controller (if you want to know the details,
- mail me privately).

- In theory, yes; in practice I doubt it. You'd need software support in
- Executor to make it work (unless - maybe - you managed to hook it up to a
- standard PC floppy controller - and I have my doubts since I believe that
- the special 800K was more a function of the Apple floppy controller than
- the drive) and I can't see that it's worth ARDI's while to do that as
- things stand. If anyone knows different of course, please feel free to
- correct me.

- I agree entirely.
