The H80P's small size makes it very useful for situations
where a temporary twisted pair network is needed, and only AUI
ports are available. It is handy as a piece of test equipment that can
be easily inserted into an AUI backbone to provide a test port, and
then removed after the testing is done. The H80P Personal Hub
takes up minimal space, uses minimal power, and is rugged enough
to be carried in a coat pocket for possible emergencies.
