Atari games Repair Logs
Model: Any old Atari game with the Big Blue caps in the bottom of the cabinet. Symptoms: Locks up, reboots randomly, humming in speaker, and more.
The big caps in the bottom of the cabinet are notorious problem parts and should be replaced if you aren't sure they have already been replaced.
While checking the power supply be sure to also check the audio/regulator boards as they are bad about having cracked solder joints.
Model: Several different Atari games Symptom: Bad GAL chips
The GAL chips on the Atari arcade games are set with their protection bits on. This precludes reading a GAL chip from a working board to fix a dead one.
Replacement code for burning your own GAL or PALCE chips can be downloaded from the Atari GALlery web site for the following games:
- Guardians of the 'Hood
- Moto Frenzy
- Pit Fighter
- Relief Pitcher
- Road Riot 4WD
- Skull & Crossbones
