chicken head

[Commodore] n. The Commodore Business Machines logo, which strongly resembles a poultry part. Rendered in ASCII as `C='. With the arguable exception of the Amiga (see amoeba), Commodore's machines 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'), in which a `chickenhead' is a mutant with below-average intelligence.
