After some time, is always good to talk with you again.
Thanks for the reply.
This information coming from you, one of the DCS / OGR forum gurus,
(I'm sorry for the term "guru"; I don't know if that is the correct word in English, but it means a person of total trust and knowledge on a certain subject), I fully accept.I understand that I can install the PS3 / 2 board in my Challenger loco
I will follow your instructions with extra care.
