I will check out the difference between settings in .PRJ and .3DS files. I have had a quick check in the manuals but could not find any guidance on the priorities of the settings. When I was experimenting I expected the .SET file to be the ultimate override. I also found inconsistencies in the operation of head/tails but put it down to my deviant hardware. (BTW thanks to all for help with previous problems. I have exchanged Hercules XP for a Targa+ to great effect. Still have some problems regarding sync and occasional bad frame but just looking into that now. Question – Will a Diaquest or external TBC improve over the AG7750 intenal TBC?). I will update my diagram tomorrow and send tomorrow. Martin Bowring
