chicken head

n. [Commodore] The Commodore Business Machines logo, which strongly
resembles a poultry part (within Commodore itself the logo was always called
chicken lips ). Rendered in ASCII as C=. With the arguable exception of the
Amiga , Commodore's machines were notoriously crocky little bitty box es,
albeit people have written multitasking Unix-like operating systems with
TCP/IP networking for them. 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.
