Looking for Tesoro Conquistador schematic

[Stefano]

Hi all.
I've recently bought on Ebay a used Tesoro Conquistador (not uMax).
I was wondering if anyone out there has its schematic,or any other info about it.
It doesn't have GB capability so, if the modification would't be too difficult, i could try to add it.
In any case, the schematic would be useful in case of future problems debugging.

Thanks
Stefano
