The chip is in the supplement of chip codes that was released a few months back. The chip is listed as PW-UO TWO COMETS if the comets are tailing clockwise as in my picture... and PW-UP COMET MIRROR if the comets are tailing counter clockwise like yours Rog. Which brings up another question... On my PW-UO that is pictured here with the comets trailing clockwise, the reverse of my chip has the comets trailing counter clockwise as in PW-UP. Does yours?
