Böhm Dynamic 4x9 Expander, Modul + Böhmat PM1

I think these units are working well but it's too difficult to me and tired about testing.
But I'm not quite sure its perfect. So selling as is / non functioning.

The Böhm Dynamic 4x9 is an organ expander, sound modul. Comes with a soundcard. Lights up, buttons are works, one time heard trumpet sound but then I lost in menu....

The Böhmat PM1 is maybe a programmer, arrranger?? This one is still a mistery for me. Lights up, buttons, led panel works.

As for cosmetics: There are scratches on body of both, but anyway good condition. 

That's all I know about  these units. I'm not interested enough to find out how these are working. 
Give me an offer if you interested.

You can find german manual of the 4x9: 

And there is a pdf brochure in english on organforum.com:


Voltages are 220V!
