Wow! thanks for all the great info. Looks like the boards I have are SOO low grade, they don't even have anything like those on them that i recognize from the google link provided above. I will double check them though. So far what I have are all out of dvd players, remotes, phones, satelitte receivers and power cord ends I have 3 tvs to breakdown, and 2 vintage Mac Classics complete with mouse, keyboards & 1 apple printer.
