Installation instructions:

There are two different EPROM sizes used for the U7 Sound ROM and the W6 jumper needs to match the EPROM size needed for your game.  If U7 is a 27C1001 then the jumper at W6 should be installed.  Earlier games where U7 is a 27C512 EPROM should remove the jumper at W6 for proper operation.
