So only the datasheet is wrong, not the schematics of the CBM-II 
computers. Right now I'm busy with the final check of the SCH for 
the 720. Remembering your post I checked these connections and they 
were just like the schematic said. 


As said, I'm busy with the final check. When done I'll upload the 
results: SCH and LBR containing the needed stuf to create the 
boards. Next I'll do the SCH of the 610.

After that I think I will find out for my self what everything does 
and then will use this material to create a more modern board. This 
will be open for discussion and forks.
