Title: Namco Galaga '88 PCB Repair Log
Post by: ataritoobin on April 14, 2013, 07:22:44 AM
Elgen's fantastic repair logs have inspired me to start going through my stack of PCBs in need of repair.  :D

Apologies for the crap cell phone pics.  Luckily this one is pretty straight forward.

Upon boot with Test Mode enabled, a RAM6 ERROR was displayed:

Let's take a look at the Atari version of the manual:

Let's see what that asterisk means:

Sounds straight forward enough!  Here's the culprit a 5165 RAM at B2:

Removed socket, added a socket, and repaired a bad trace, replaced the 5165 with a 6264:

Back from the dead!
