Micro-Processing Unit (MPU) was evolved to an 8-bit performance in the 1970s, and the main control unit of the AT-20P was evolved from the minicomputer to the microcomputer, and the mechanism control unit was evolved from the IC circuit to the LSI circuit. In addition, the control system of AT-20P was evolved from hardware control to software control.
AT-20P was realized the ATM service for the first time in Japan, and also contributed to the practical application of mechatronics that was evolved mechanisms and control highly.
