Damn, i should have been thinking....
 
     was that card in the edge connector by any chance the monitor
electronics???   does the main board have a card edge connector on it??
 
     better yet, look on the cpu board for these numbers:
 
                   either    140P82629A
                       or    140P82664A
 
     if it has either of those 2 numbers, then you have an 820 and
are in luck.  
 
     820-I machines do not have an edge connector on the main board.
