I'm not sure Kenwood made one for it themselves, if so I can find no record 
of it. I see a lot of people using the Comspec T32 or t64 I believe it is 
boards with them, I've looked all over and as of yet haven't found any 
reference at all to a tone board for the TR-7850 specifically. It makes me 
kick myself, I had a comspec T32 back when for another project a while back, 
didn't need it for that and gave it away, now I wish I kept that board.
