Subject: IGT 4th of July Slant Top

I have an IGT 4th of July slant top game with a #12 error code which is the battery. While I'm waiting on that, I'm curious. I want to run some output tests on the coin hopper etc, but I don't have a manual and can't seem to fine ones on line like I did for my Double Diamond S+ without buying it. I figured out how to make the reels turn, but that is the only output I could figure out. I also have coin comparitors ordered for both machines. Anyone know how to make coin hopper feed via turn key?

Test #3 should be the hopper test.

To find the exact tests, you will need the PSR sheet for your SP chip. On the MPu board, there are 2 EPROMs that should be labeled. One is an Reel Prom, and will be labeled with a number starting with SS. Second is a Game Prom, that will be labeled with a number beginning with SP (like SP1272, SP874, etc).
