Halt and catch fire; Halt and Catch Fire (disambiguation)
<humour, processor> (HCF) 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 Motorola6800microprocessor 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.

SEVERAL COMPUTER MACHINE CODE INSTRUCTIONS THAT CAUSE A COMPUTER'S CPU TO HALT
Halt and Catch Fire (HCF); Stop and Catch Fire; Halt and catch fire (computing); HCF (computing); Drop dead (computing); Drop Dead (computing)
In computer engineering, HaltandCatchFire, known by the assembly mnemonic HCF, is an idiom referring to a computer machine code instruction that causes the computer's central processing unit (CPU) to cease meaningful operation, typically requiring a restart of the computer. It originally referred to a fictitious instruction in IBM System/360 computers (introduced in 1964), making a joke about its numerous non-obvious instruction mnemonics.
