The interactive graphic system consists of a keyboard for introducing drawing data, a plotter for recording the figures, a microcomputer, and a memory unit that are constructed as a unitary structure which features small size, reduced cost and enhanced operational performance. Further, the interactive graphic system is so constructed that application software packages can be freely exchanged to diversify the functions.
