1. The archetypal really stupid application for an embedded microprocessor controller; often used in comments that imply that a scheme is inappropriate technology (but see elevator controller). "DWIM for an assembler? That'd be as silly as running Unix on your toaster!"
This is not usually to be taken literally but, to show off the expansion capabilities of the Risc PC, Acorn Computers Ltd. built a seven-slice machine (which they called "the rocket-ship") and installed every imaginable peripheral. In a spare drive bay of the top slice they installed a toaster. This machine was exhibited at various shows where it attracted attention by occasionally ejecting a pizza.
