5-3-1 Outline
The main micom peripheral circuit is composed of 16bit Micom (MIC1 ; TMP93CM41F), 8M EPROM (MIC8 ; AM27-
C080) for Microcode and data save, 512 byte EE-PROM (MIC5 ; KS24C020) 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
(MIC7 ; 74HC00) for selection of ex-ternal device chip and 20MHz clock oscillator for micom operation. The Micom
(MIC1 ; TMP93CM41F) 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 exe-
cute the corresponding commands after initializing the devices connected with micom on board at power on.
