So there is no PSU schematic in there. When I got a 128D from a fleamarket one year ago, I had to first disasseble it because the disk drive had a mechanical failure. After that I installed the drive power connector in a wrong way, so there was a shortcut between the 5V and 12V line. This caused the crowbar of the 5V part to shutdown the PS completely. While searching for the fault inside the PS, I started making my own schematic of it, but probably it's only half finished because I realized the real problem soon enough ;-) Nicolas - This message was sent through the cbm-hackers mailing list.
