 note = {As a teaching material on the hardware of a personal computer which is an urgent problem in the training of techical/industrial art teachers, the authors developed drawing system of elementray figures (a square, slash, circle and sine wave) ; the system is constructed by a D/A converter and a X-Y recorder.\nAs a teaching material, the main purposes of the system are as follows.\nThe trainee teachers will\n1) understand the theory of D/A converter.\n2) be visually confirmed thet a digital value is scatterd.\n3) understand thet there is the I/O port address in a personal computer; and how to set up the address.\n4) acquire the basic skill to treat the figures digitally, which are essentially analogue values.\nThis system satisfies these purposes through exercising drawings by partially changing the program and the recorder sensitivity., 紀要論文},
