Bally score reel relays

On Bally EMs, separate relays score the 10, 100 and 1,000 reels, each with switches for its reel, its chime and the carry into the next reel (the 10s relay may also step a 00-90 unit or a feature). The 10,000 reel moves only on a carry from the 1,000 reel, so it has no relay. Two more relays reset the reels, each handling two players (eight reels).
