Deger single-winding flippers on Playboy and Monday Night Football

These two games use a two-lug, single-winding flipper coil. Pressing the button feeds 50 V DC until the normally closed EOS switch opens; the coil is then held on about 9 V through a 1N5404 (400 V 3 A) diode mounted on the coil, alongside the usual 1N4004.
