Hi Dangling - go to
www.wilcopub.com - they have or are just about to bring out a dedicated full blown 767 sim, and you can download the manual to it - it looks pretty smart and will give you a good insight to all the major procedures. It takes a while to download, and forever to print unless you have a laserjet, but if its a 767-200 sim you are after, these are your people.
Id be interested to hear how you get on with it if you but it..........
