Hello, i just came home and i took from the basement the battery from a damaged Powermac 7500. I connected to the performa 6116 and nothing happened. But i tried the double tap boot with the power button. Before i had tried that many times with the reset and nothing happened. With the power button the performa started again! The disk was automatically ejected and the machine booted to mac os. The battery was reset to 1956. I turned off the computer again, then turn it on again and nothing again. I tried again the double tap boot with the power button and again the performa started but again the date was reset to 56!
