Re: Asteroids - Bad Vectors but plays OK

This afternoon I started to look at a basket case Asteroids PCB which had lost of missing parts as I'm getting frustrated with not being able to fix the one with Vector RAM issues.

Anyway, after filling in the many gaps, 5 of the 6 RAM were bad and replaced, the game now boots into game over mode but with corrupted vectors.  Can anyone point me in the right direction?

The self test switch does not seem to work, so I'll have to look at that as well.

Any ideas?
