Knut,

    Do not worry.  Please do not feel bad.  I had no chance to reply back 
about RGB card's jumper yet.  Right now, I concentrate to study DHGR while I 
use second RGB card.  When I have some time left, I can take a look at first 
RGB card.  I will let you know the status.
    We need to be patience when we study how DHGR works in RGB card.  We may 
be able to write a short routine in Applesoft BASIC code or assembly code.
