1819Machine Operation:
191. Press num-enter then END then .(period key)   (the displays will flash 400000)
202. Press num-enter
213. Insert a coin, credit will be registered
224. Hold X and start game. When 00 is flashing, release X
235. Press any of QWERYUIOASDFGHJKLZ-='; to simulate scoring shots (T will tilt)
246. Press and hold X to simulate losing the ball
257. When score starts flashing, release X and go to step 5 to play next ball
201. Press .(period key) (this sets up nvram and the displays will flash 400000)
212. Insert a coin, credit will be registered
223. Hold X and start game. When 00 is flashing, release X
234. Press any of QWERYUIOASDFGHJKLZ-='; to simulate scoring shots (T will tilt)
245. Press and hold X to simulate losing the ball
256. When score starts flashing, release X and go to step 5 to play next ball

2727Notes: Do not play more than one player because the machine will try to
2828rotate the table, and the motor circuits are not emulated due to lack of info.

3434ToDo:
35- Battery backup
36- Outputs
37- Simulate motor circuitry and sensor feedback
38- Verify labels of East, West and South on the display panel
35- Lamp outputs
3936- Possibility of a rom missing (most likely it is optional)
