Just got myself this hr16 from the fleamarket… the owner bought it used already and had no clue what he’s owning. Now it’s my turn and.. I have no clue^^ Most stuff seems to work somehow, except for one of the pushbuttons next to the chip holders I need to replace. But— does anyone know whose work this is? Would be awesome to get some info on how it was meant to work as I’m still figuring out how to use it, and of sth is broken or meant this way. Thx in advance
