Hi there, I am looking for photographs or replacement parts for a Unitron U2000/Linden Series One keyboard. It was working however in doing some testing with it I think it blew the controller chip, which is a 2732 EPROM. I've changed all the other chips with no success. Was hoping to find a reference photo just to make sure I haven't messed anything up, or if possible a dump of the controller ROM. Not urgent but hoping to get this running again someday soon. Basically right now nothing works except CTRL-RESET Thanks!! Brad
