Title: CompServ SD/FF II
Post by: flaviosr on July 12, 2009, 04:42:39 PM

Hi,
TRAGEDY!!! The card stopped SDing... I tried different configurations but my monitor always reports 15 kHz as vertical (obviously it cannot work with frequencies below 30 kHz even if it can report which one is in input)!!! Can somebody help? Can I try changing something? I see that some chips are not soldiered... as the socketed big one near the backplate...

The card stoped working by itself or did you change/move anything ? Might just be a bad contact somewhere. Are the jumpers configured correctly ?

I was trying to make it work! I mean that the card was working apart that, when in 640×512, the bottom of the screen was cut!
So I tried to change the jumpers and then the card started not to work in interlaced mode... then not working at all... giving an output at 15 kHz.
I do not understand the manual in German but now I have the jumpers in their original position (I mean like when they were when I received the card), i.e. j1 pin 2+3 closed (the two nearer to the Zorro connection), j2 and j3 open, only da3 closed.
