Hi all,
I just got a Galaga dropped off for some work, and it also has a booting issue.
When powered on it has the usual boot up strange graphics show for about 3-5 sec., than for a split second you see the star field and text: RAM OK. Then the screen displays all 0s.
I removed and cleaned the legs on all socketed ICs and also edge connector with no change. I checked the voltage on the PCB(5.2vdc). It also looks like someone has installed several new IC sockets(very professional job). Any ideas?
Thanks for any advise
Aaron
