I apologize if you're an operator and your MK cabs are set for pay-to-play, because you're going to have people changing your machines to Free Play. With the recent discovery of the 20+ year hidden 'EJB Menus' in MK1, MK2, and MK3, there is an exploit that can be done to turn any MK2 or MK3 cab from pay-to-play to Free Play. I explain it all in the video below, but in case you don't want to sit through it or you can't watch it, it all boils down to this.
Under normal circumstances, if you access the service menu and do a 'CPU Board Test,' after it's done the board goes back to the menu so you can continue with more tests. The caveat here is when you are in the EJB menu and you do the 'CPU Board Test,' when it's done, instead of the board going back into the EJB menu, it reverts back to the regular, normal service menu, as if you pressed the button behind the coin door. The EJB menu has no access to allow you to make pricing changes. When the board reverts to the regular menu after the board test, you now have that option! So basically, as long as the dip switches are set to CMOS coinage, you can change any MK2 or MK3 cabinet from pay-to-play to Free Play by doing the above steps.
