Yes, I did. Anyways its just a dip setting but you loose attract mode and the monitor will burn in eventually. Not really an issue with a home use machine but I prefer to swap in the freeplay attract rom and not worry with it. Its only one rom to change.
Or put a credit switch in it. All my machines have one. Makes having guests over to play easier - much more consistent for them (not all games have free play). I have a momentary switch tucked into the coin return, wire goes up through the drop slot and to the coin mech micro switch. Easy.
