I tried to visit some of the sites he listed as reference material , but either they don't exist anymore or I just can't get to them .Judging by the code , it does seem to be a complex and accurate instrument , and if someone can figure it out , great. My nasal 'experiment' is meant to appease those who want it working , (and to see if I can do it ), but it wont be anywhere near as complex as the MK-VIII. I did try to contact Jean long ago , to see if there were setting that needed to be changed for individual aircraft (when I added it to the Bravo),but no luck there . I will continue to poke around with it , I think it should have more obvious user settings.... and thanks for looking into it . Cheers
