Hi.
In my opinion, they are useful things. Inside there is no more
than a chip doing the conversion from a parallel port to an IDE port.
In www.shuttletech.com you can find the chip used. With them you can
have an external CD (5.25" units), useful for portables.
They may or not contain a power supply from AC. If not, probably
they are supplied from the +5V in the kb connector; if this is not available
(some old portables) you would have to open the portable and get +5V (and
pray so that the power supply delivers enough power).
