from "The Hacker's Dictionary":
"HCF /H-C-F/ n.
Mnemonic for `Halt and Catch Fire', any of several... machine instructions with destructive side-effects, supposedly included for test purposes... The MC6800 microprocessor was the first for which an HCF opcode became widely known. This instruction caused the processor to toggle a subset of the bus lines as rapidly as it could; in some configurations this could actually cause lines to burn up."
