Greetings! I love my Imacs and i hated the fact that the source wanted a damn $20 for a clock battery. I wasnt going to spend $40 plus taxes on two old imac G3's. So I bought this 'AA' battery holder and soldered it to the prongs giving the imac a mere 3Volts. My Next issue was that i have to put the batteries somewhere and since the plastic cage wouldnt fit between the hard drive and the drive bay I pulled the entire hard drive CD rom caddie and placed it there. With my second G3 i did the same but the batteries seem to smell a little bit so im fearing somethings up. Never the less my Indigo Imac holds time! MY imacs are: Indigo 350Mhz PowerPc G3 512Mb RAm 16gb Fujitsu Hard drive CD-Rom 10.3.9 Panther The Tangerine 400Mhz 1gb Ram 80Gb WD hard drive DVD-ROm 10.4.11 Tiger What do you think guys? Just thought i'd share.
