across diode CR3.

Problem: After warming up, partial vertical
lines begin to fill the game's screen and
the game starts to beep, indicating that it is
in the RAM self-test.

tor on pin 13 of the Potato chip (vertical
scrolling chip) at location 3K on the PCB.
2. Replace the type-? 4LS7 4 chip at loca-
tion 7L on the PCB with a type-74$74.
