(1) Outline
The main micom circuit is composed of IM flash memory (DIC2) to bosting system and data saving, 64bit
SDRAM (DIC5) for temporary data read and write
The Micom (U1, ES6698 & ES6629) mounted in main board analizes the key commands of front panel or instruc-
tions of remote control through communication with Micom (IC601) MPD790006GF of VCR an d controls the
