No Joanna, I think you are wrong.
In this case it seems that Terrasoft wants to
tax all boards that are capable of running YDL ( with their
contributions of course ) that are resold through OTHER
vendors regardless of whether or not that board ships
with YDL.
In the Amiga case the "Amiga Certification Scheme" would only be applied
if that board was to be sold as an Amiga.
One you get a choice over ( don't sell it as an Amiga ) the
other you do not ( its capable of running YDL therefore it
must be taxed ).
Thats how I read it anyway.
