Ive got two problems with my galaxian board. Ive swapped some 74xx chips per the troubleshooting manual, but it hasnt helped.
Problem 1: On the attract screen, when the ships slide across along with the scores, the ships are way high on the screen, while the scores are in the correct location.
Problem 2: When the enemy ships dive, when the flip, they dont look right, also, they disappear about half way down the screen.. Im thinking it could be a ram problem..Due to the delicate nature of the board, I wanted ask for ideas before I desolder any of the ram chips..
Thanks for your help,
Andrew
