<graphics, abuse> The Commodore Business Machines logo,
which strongly resembles a poultry part. Rendered in ASCII
as "C=".
With the arguable exception of the Amiga, Commodore's
computers are notoriously crocky little bitty boxes (see
also PETSCII). Thus, this usage may owe something to Philip
K. Dick's novel "Do Androids Dream of Electric Sheep?" (the
basis for the movie "Blade Runner"; the novel is now sold
under that title), in which a "chickenhead" is a mutant with
below-average intelligence.
