Information
has gloss	eng: In computer jargon, a killer poke is a method of inducing physical hardware damage on a machine and/or its peripherals by the insertion of invalid values, via e.g. BASICs POKE command, into a memory-mapped control register. The term is typically used to describe a family of fairly well-known tricks that can overload the analog electronics in the CRT monitors of computers lacking hardware sanity checking (notable examples being the IBM Portable and Commodore PET; a similar trick is reported having been done to Atari ST displays).
