Hi Pinside
I wanted to set my Spirit of 76 on Free Play and wanted to share my success with you.
I followed the guide here, http://www.pinrepair.com/em/index3.htm#free. The Spirit of 76 uses the Gottlieb half-moon credit unit. Opening the Scorebox, I used a paper clip (I didn't have a small alligator clip) to permanently short/close the switch (see picture with a blue arrow, the switch is closest to the increment coil) when the credit unit was at "zero" credits. This enabled enable free play.
I am likely being repetitive for some, but thought it would help some owners that hadn't tracked this information down.
