Depends on which bill acceptor you have. If its a Mars AE 2411, it can be flashed with new software if the first 3 digits of the serial number are atleast 409. Mars started manufacturing the flash port style the 40th week of 1999. If its before this date stamp, you must change the pcbs.
Actually, I just read a sticker on the side of the dollar bill compartment that says "New currency ready"!! So I guess I should get a new 5 and test it.
