Re: 2114's ->RE: BattleZone probs....

I had problems recently with 2114s that passed the self test in Galaga (RAM
OK) but the game would go belly up. I posted in RGVAC asking about the
self tests but most of the info I got back was about the locations not
matching or bootlegs where the RAM address was moved but not the self test
address (but then how could it pass???). It appears that Galaga spends a
lot of time testing them at boot up but I don't understand what kind of
tests it's doing.

Yeah - the part number was 2114-AL that I used and it gave me problems. -
And yes, funny that Mark would mention checking the roms to make sure they
were seated properly in their sockets. My Battlezone complained about a
bad rom - all I did was push it in with my thumb (I could here a small
click) and then it was happy.
