1. A computer sufficiently small, primitive, or incapable as to cause a hacker acute claustrophobia at the thought of developing software on or for it. Especially used of small, obsolescent, single-tasking-only personal machines such as the Atari 800, Osborne, Sinclair, VIC-20, TRS-80, or IBM PC.
2. [Pejorative] More generally, the opposite of ‘real computer’ (see Get a real computer!). See also mess-dos, toaster, and toy.
