The main micom peripheral circuit is composed of 16bit Micom, 2M EPROM for Microcord and data save, 1M
SRAM for data read/write on running, 512 byte EEPROM for permanent storage of data needed at power off,
MIC4(74AC573) to latch only address in the bus where address and data are mixed, address decoder for selection
of external device chip and 20MHz clock oscillator for micom operation. The micom(MIC1, TMP93CS41) mounted
in main board analizes the key commands of front panel or instructions of remote control through communication
with micom(FIC1, LC86P6232) of front and controls the devices on board to execute the corresponding commands
after initializing the devices connected with micom on board at power on.
