Okay, so I got a Defender a few months ago. Been working on it while I can, but due to lack of funds and time, it's been a long ride.
So, when I got it, I reattached the power chord, and the game played VERY sporadically (double sprites on screen, etc) and then eventually just started showing a rug pattern. The previous owner mentioned a ram problem, so I purchased a confirmed working RAM board from one of the great KLOV'ers on here. It didn't fix the game.
His knowledge led him to believe that I had 4116's bad on the main board... which seemed very believable. He directed me to switch a few around to see if anything changed... and it did. So, I knew my RAM chips on the main game board were bad.
Fast forward to today. I just got a 4116 to 4164 kit in the mail with 24 brand new 4164's.. just installed the power adapter and chips, and booted to a nice blue screen... which is even worse that before. No repeated boot sounds like last time, not a hint of a rug pattern....nothing.
What am I doing wrong? I mean, I've dumped $80 into getting this machine working, and it is still DEAD... please help.
Also, to advise, I am without a multimeter.. It's back home in Atlanta... and I'm at college.
