From the enormous hacker dictionary:
dink /dink/ adj.
Said of a machine that has the bitty box nature; a machine too small to be worth bothering with -- sometimes the system you're currently forced to work on. First heard from an MIT hacker working on a CP/M system with 64K, in reference to any 6502 system, then from fans of 32-bit architectures about 16-bit machines. "GNUMACS will never work on that dink machine." Probably derived from mainstream `dinky', which isn't sufficiently pejorative. See macdink.
