Well I have a Performa 475 here, got this one from jt. First time I flipped the switch I get a somewhat slow death chime. If I turn it off an on quick I get a happy chime and then a quicker death chime. Missing vram so I grabbed the stick from my LC to throw in there. I think a recap and a battery will fix this machine. Just curious to what you guys think. I know these machines have a fit without a pram battery so what can I do to get around a battery for now until I can get one?
