From Jargon File (4.3.1, 29 Jun 2001) [jargon]:



  HCF /H-C-F/ n. Mnemonic for `Halt and Catch Fire', any of several
     undocumented and semi-mythical machine instructions with destructive
     side-effects, supposedly included for test purposes on several
     well-known architectures going as far back as the IBM 360. 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. Compare {killer poke}.
