The problem is that the 1551 schematics has very little with the PCB I've got in my own 1551. Maybe take a look at the photo:

Instead of 6523A there is 6525A, and the jumper (JP1) is located at different PIN - in the middle of the chipset and not at the edge. I'm also not quite sure whether the JP1 it is really cut open.
Any ideas would be really, really appreciated, the software reverting to 8 with every reset is more than annoying. Wink
