Re: Re[2]: Star Wars PCB help

I had some wierd things happening on a set I was working on a while back, I
think it was a bad 74ls374...there are 4 of them together on the main board
not far from 5H Ram.Might be worth checking. I also found 4x 74ls00's dead
on the same board which was very strange!!
