The Superdrive, also known as the FDHD drive, is an Apple 3.5 inch drive
that supports Apple GCR disk formats (400K single-sided, 800K
double-sided) and IBM formats (720K, 1440K). It was standard as the
internal drive on all of the later 68K-based Macintoshes. The Macintosh
128, 512, and Plus can not use it. The Macintosh II and Macintosh SE
can be upgraded to support it, by installing the SWIM chip in place of
the original IWM chip.

An external Superdrive can be used on some Macintoshes, such as the IIci.

The external Superdrive will *NOT* work with any model of Apple ][
(including the //gs) unless you use the Apple Superdrive interface card
or a third-party equivalent. In particular, it will *NOT* work with the
built-in controllers of the Apple //gs, //c, or //c+.

(The documentation claims that it won't work at all. I suspect that it
might work in GCR mode, but I haven't tried it.)
