I am very interested in the hampod, but I think it takes the only computer
interface port.  If you can use both a hampod and a computer at the same
time, it would be an option.

Rob makes a perfect solution with his Hampod.  Why not just go with it?

I talked with Mosley about four or five years ago and they were not making
that talking rotor control box any longer due to parts not being available.
