PRINCIPLES OF OPERATION
When the ROM cartridge is removed (see Figure 2-29), the CAR terminal of the gate array (6C) receives a HIGH
signal. Then the DISC terminal outputs a LOW signal, and the ROUT terminal outputs a RESET signal.
The remainder of the sequence is similar to that when a ROM cartridge is mounted, so please refer to the
preceding page.
