Ohh, thank you! Now I should be able to tell what version my motherboard and trackball are!
Now my only remaining question is how to tell if the battery boards are the new version or not… I don’t know if anyone would be willing to take close-ups of some v1 battery boards…? I can see the new battery boards in the picture on their shop, and they look similar to mine, but I don’t know if the v1s also look very similar or not.
