Rev 1 has a few small bugs built in. Some holes are too small and the silkscreen was not always easy to read. A few traces have been optimized.

I would like to have more than one to be able to equip my bridgeboard in my Amiga with it. Therefore I cloned an old graphics card. It has few parts and …
