MELCOM88

This office computer was announced by Mitsubishi Electric in 1972. It used ICs for main memory, and had performance 15-20 times better than the MELCOM83 in terms of arithmetic speed, and performance 3-20 times better than the MELCOM83 in terms of overall capabilities. It was the first machine with a practical multi-billing system in which multiple terminals were connected so that multiple operators could do billing at the same time.
