    Please stop using txt speak here in the forums. Please check your private messages (PMs) about it.

    On your question, you might get lucky here if somebody has a copy. But you might want to check with your local libraries or other resources.

    You might also try PM'ing m.s.j with your question. He works in the power industry, I believe.
