So, I dropped in new 7-digit LED displays into my Meteor running the new code. I didn't make the 2021 hardware myself (just bought a plug and play kit). What exactly do I need to do to get the 7th digit recognized? The game's wiring has already been modified. Thanks

Your code for Meteor is outstanding. I enjoyed playing the new code for 6 months but my Meteor is no more. I bought it to do a Star Gazer build that is now well on its way. When it is all said and done I’ll be left with 2 Classic Stern games (Seawitch and Star Gazer). Are you planning to redo the code on those? If not, I have a nice plug and play setup I am willing to part with for somebody wanting to experience the new Meteor code with little effort.

I made one of those when I had my Meteor. Works great. That way you can just utilize your cabinet speaker and don't need anything else. I think the instructions are on pinside somewhere.
