Notes:
------
- P20:R LIGHT - There was a light under the roller for the dedicated cabinet.
- If you're converting Major Havoc to run in a cabinet with a vertical
  monitor, you can get the game to display correctly by switching the
  X-OUT and Y-OUT pins, and/or grounding the X-INVERT and Y-INVERT pins.
- Once you've got the game displayed correctly, you can then fiddle with
  the XSIZE and YSIZE pots on the main board to resize the picture until
  you get something you like.
- This doesn't work on all monitors, so your mileage may vary, not only
  from monitor to monitor, but from board set to board set.

				  2-Coin Minimun**

-------------------------------------------------------------------------
* Manufacturer's recommended settings
** This game has the ability to select the 2-coin-minimum capability, which
requires the player to pay for two games in advance.  If you want this 
capability, short pin 6 on 13N to ground by soldering a short piece of wire
from ground to this point.
