摘要

An apparatus for selectively operating a plurality of computers connected to a common video monitor, includes a single data I/P device for inputting data and instructions to the plurality of computers, a main control circuit which is connected to the data I/P device, and a selection circuit for selectively providing the data and instructions from the data I/P device. The main control circuit outputs a computer selection signal to select one of the plurality of computers to which the I/P data and instructions are to be transmitted and a video selection signal to select the video output of the selected computer to allow display on the common video monitor. <IMAGE>
