Seeburg starting with the M100A (1948, the last 78 rpm juke they 
made)  had a tonearm with a cartridge on each side. All the box had 
to do was reverse the direction the record was playing them move the 
tonearm to play the other side of a record. They kept that design 
through the 70's or a bit longer with the records in a vertical stack.
