    Have you contacted Ryka Enterprise about that information? Even if someone here could come up with the schematics, the contents of the EPROM's is proprietary information and would only be available from the manufacturer.

    Hmm - I did a Google search for Ryka Enterprise in CA, and came up with nothing. ???

    If there is no other contact information, then try taking some detailed photos of both sides of the circuit board and post them, maybe it can be figured out.
