Schematics TF-900

Hello!
I'm sending photos for you

[kt315]

thank you. real discovery for me that is TM-800 board. it is due precise copy of the one. if you are interested I can upload photos of TM-800 but you can find these files in the forum. this is mean whites would be gone on one step far made TM-808 -- ??, I do not know... then you can take whites 3900 di pro schematic and draw TF900, there have not many differences in my opinion.

The early White's TM600 and TM800 were made by Discovery and were the same design as the TF900. The TM808 is an entirely different design based on the 6000.
