Principles of Operation
Figure 2-28 shows the -RESET pulse oscillation process after you remove a ROM
cartridge. The -CAR terminal of the gate array (6C) receives a HIGH signal, the
-DISC terminal outputs a LOW signal (1), and the -Rout terminal outputs a
-RESET signal (2).
The rest of the process is similar to what occurs after ROM
cartridge installation. See the description above.
