Thanks Bruce.
I suppose the overjoy is now (somewhat), overshadowed by the knowledge I've just purchased a partly faulty 861v6 and.. not sure if there's much I can do about that now tbh but, that is another story...
I'm just wondering if there's anywhere else or somewhere in MConfig, that could be causing D4 on MD2 to be silent. Is there a setting somewhere... anywhere ? I haven't checked D6 yet but if that's fine too, how could just 1 output be "gone" ? I just don't get it..
For the benefit of future resale, maybe I might need that IE44 card price after all, as per my PM to you Bruce! If you had time and could still check pricing/availability, I'd really appreciate it !

Thanks again.
Andrew
