IGT Sizzling sevens dip switch

[clown2948]

I picked up 2 IGT Sizzling sevens dollar machine. I need to know if they should have a dip switch on the main board in slot U1. On the back on the board it shows dip switch settings. Can anybody tell me if the dip switch is some other place. This is a stand alone progressive machine. I have not tried to turn on this machine yet.

There are two common versions of the cpu board on the S+.  One has the older 10 Mhz crystal and it does have a volume knob and dip switches.  The newer 16Mhz board does not have dip switches nor does it have the volue knob on it.

Thanks for the fast reply. I have the 16 mhz board that does not have a vlumn control or dip switch. Just a question ,than why do they still put the paper with the dip switch settings on the back of the board if you can't set them. just wondering.

The metal tray that the board sits in is generic for the S+ machines, regardless of whether or not there's a 10mhz or 16mhz board in it (the tray and the transformer work for either type board).  It's quite possible that the machines originally had 10mhz boards in them, and for whatever reason they were changed to 16mhz boards (using the same metal trays).
