boat anchor: n. [common; from ham radio] 1. Like doorstop but
more severe; implies that the offending hardware is irreversibly
dead or useless. "That was a working motherboard once. One
lightning strike later, instant boat anchor!" 2. A person who just
takes up space. 3. Obsolete but still working hardware, especially
when used of an old S100-bus hobbyist system; originally a term of
annoyance, but became more and more affectionate as the hardware
became more and more obsolete.
