I am trying to get my 4n1 v3 Pac board running but have an issue.
I modded a working Pac board to the Souzilla 4n1 v3. It worked but I needed to replace the IC sockets at 4K and 4N with dual swipe sockets to use the NVRAM adapter.
In my haste (which is never good when doing board work) I lifted 3 traces on 4K (pin 2, 11, and 14 ) which I decided to just jumper on the solder side. I jumpered pin 11 on 4K to pin 9 on 4H and pin 14 on 4K to pin 6 on 4H.
4K
Pin 2 to pin 2 on 4L
Pin 11 to pin 9 on 4H
Pin 14 to pin 6 on 4H
I compared continuity on another working board I had.
Now when I power it up without the NVRAM adapt. and just the RAMs that are in their originally I get the following.
Here is the back of the board where I jumpered.
I tested the RAM at 4K and 4N in another board so I know they are good. I also tested continuity between RAMs and 4H and confirmed with another working board.
Any suggestions?
