In theory, this could one day provide a key component of any nanoscale electrical circuit-a way to mechanically turn the current on and off or change its direction.

He was just sort of interested in getting the Apple II on a printed circuit board so he could have one and be able to carry it to his computer club without having the wires break on the way.

This paper introduces one way to design scheduling logic circuit with medium-scale integrated counter at the core and based on MSI.
