There should be three pins. Two on one side, one on the other side. That lone one should be the -. Of the other two, one is +, the other is self destruct. Be sure to mount your new csppc to the fast slot for a nice fireworks show before you try

nice pics, but how have u connected the pins to the coin battery holder?
u used only the 2 on the left side (and ignored the signle right one?) and on the upper one u put a diode too? |

diode is soldered on "spring" contact directly, original contact was cutted and isolated from under (as it was in wrong place) |

btw, the diode needs to be type: 1N914 , right?
and it has some color stripes on one end, do they need be closer to the battery of the mobo? I think the battery right? |

Any silicon diode will do (forget special stuff like germanium). Stripe goes towards motherboard. (look at lithbatt.lha linked above for an illustration)

i can only recommend to measude voltage diferencies if you have some spare diodes, as lower=better. Some diodes have really big voltage decrease. 2.8V will work, but 2.7V or lower is sometimes too low for clock circuit (remember originally there was 3.6V battery (3x1.2V))

Hay, Keropi
Please post what Diode you used and maybe where you got it too. I am going to be doing this soon and your help would be great. Thanks~ |

damn! my mobo has the alone pin OK, and the "free pin" of Chain's drawing... and the previous owner had there a set of external rechargable phone batteries... 3x1.2v if I remember correctly...
