No problem, the German was excellent. Okay, here is the bug fix:
The bug consists of a chip which is of the wrong speed type. It is
U23. I do not have my card at hand, but I believe it is located in
the second row from the left, at the bottom. It is marked as U23 on
the board, anyway. It is a 74 LS 32, but should be a 74 F 32 (Fast
instead of Low-Power Schottky).
Carefylly de-solder U23 applying the usual precautions against
static electricity, then solder the 74 F 32 in (Better: solder in a
socket and place the new chip in the socket). That's it.
Beware: Do this only if you are experienced in ICs and be reminded
that this may void your warranty.

Cheers!

Oliver
