Does anyone know if the circuit board is the same on the tour and the bold, meaning can i replace the housing on my tour with the bolds so i can install the optical trackpad

[Syco54645]

probably not.

With the very slight difference in position of the usb port, We can say with certainty that the boards are different. Besides that, the trackball connection will not be compatible with the trackpad connection if you were able to swap the case.

Optical trackpad? I've never heard of that. Is that what the Gemini uses?

Its what your 8520 uses.
