This is indeed a Miprom. However I am of the belief that the 21designation was for digital AC or DC drives. The analog drives were not designated as 21's. And a 6010 was not either. The picture is of a dispatch group controller, or an MST selector controlled 6010. I assume this thing is fixed. It would be nice if they let everyone know what the fix was. It may be of help to someone else.
