Actually I was mistaken. I just looked at the old boards and: 55-0301-00 says that it is Rev. D 55-0302-00 says that it is Rev. B On the new trackball: 55-0302-00 says that it is Rev. B I cannot read 55-0301-00 on the new ball since it is mounted. I'm confused. How do I tell if I have the new boards???? |

Another update on this. I ordered a Happ USB Trackball kit from ebay and it contained the 2 boards as well as the cables. I placed the kit into the old trackball and everything is working fine on the old one as well. It definitely seems to be a problem with the old boards. Note this these new boards also had the same Rev numbers. |
