This model uses a Z80 equivalent CPU operating at 16MHz.
Many of the peripheral functions are handled by custom designed LSIs.
As a result,the CPU only needs to process the results.
Real time clock.
Decodes the address.
Controls the SELECT signal of ROM or RAM and bank switching.
Controls the polygon motor and outputs the VIDEO signal to LSU.
I/O Port Interface.
Sends beep tones,etc.
Convert the analog signal to the digital signal.
Controls the SCAN Motor.
