The lines on the display are a fault with the video hardware. I think a couple of RAM chips are broken, but it could be some other fault. I've had the SD card working on the second Pico and have the link between them sending data, so the code just needs a finishing step to pull it all together. The case looks odd because the FX9000P is dismantled in many ways... ... https://www.youtube.com/watch?v=ROz7OsOz538
