In 1978 National Engineering Manufacturers Association released a "standard" for programmable microcontrollers, including almost any computer-based controllers, such as single board computers, numerical, and event-based controllers.
National Engineering Manufacturers Association avaldas aastal 1978 standardi programmeeritavate mikrokontrollerite jaoks, sealhulgas peaaegu iga arvutipõhise kontrolleri, nagu numbrilised ja sündmuse baasil töötavad kontrollerid.
