I don't know about Sanamon, but the sources for SanaUtil are available. The are sources for some drivers available too if you're interested in implementing a SANA-II device.
BTW, those includes on Aminet don't include the additions to the standard made in subsequent years.
Oh, that's right, I think the package I linked was SANA-II R2. I remember some documentation about a semi-official SANA-II R3 and maybe R4. Did Olaf Barthel work on those? Or was it someone else?
