| Powerbook 145b repair attempt needs help | |

Posted by: Dogmander on 2024-01-12 07:26:07It doesn't help that all (or most?) of the traces on the board go through internal layers, making them very difficult to trace out. It would probably help if someone with a fully working one traced all the paths out and did a schematic. My 145's board is fully working so I suppose I could, but I don't know what software I'd use to plot it all out.

The 140 uses the same CPU board as the 170 (and 145 too I think), but the 145B uses a different board (due to extra onboard ram). | |

The main difference is that the earlier PowerBooks have a narrower 50(?)-pin connector rather than 72-pin on the later ones. I carried out this repair on two of my interconnect boards after...
