ABSTRACT An electronic control package for a sewing machine having a frame supporting functional components such as thread handling components, a needle bar gate and needle bar, feed system, electrical actuating means for the needle bar gate and feed system, electric drive means, transformer, power supply and pulse generator. A panel supporting pattern selection and other sewing machine control means may be combined with a printed circuit board carrying control circuitry including a pattern memory means and electronics required to convert pattern information from the memory means to a form usable by the electrical actuating means for control of needle position and, if desired, for regulation of feed. By exchanging panels, the type of control and appearance of the machine may be altered as desired. By exchange of panel and printed circuit board major changes in machine feature capability and appearance may be accommodated.
