Except for the IIfx, which is handled properly... it comes with an
internal terminator that's used if there's no internal hard disk.

Slick!  Another approach to the same problem is to install an internal
terminator in a Mac that has no internal hard disk.  I seem to recall
reading that someone (MicroNet?) makes such a beast.
