Hello Stefan: of sure now the code is much more elegant and performing.
You had not still resolved the problem of collision among more button pressed: you should use the TristatePort instead of the OutputPort. The main difference is that on the Outputport you change the output state, while with the TristatePort you will change the direction. Instead of using the "Write" method you should use the "Active" property: when is true, the port is an output, and when is false it is an input.
With this trick it won't be any collision.
Good work anyway.
Cheers
