I have one of the new PPS backglasses on order and am getting ready to strip the playfield for a full clean and wax before putting a playfield protector on it. This is my first pin, so I'm spending way more money on it than makes sense.
I've also installed the Rottendog 327 MPU, Rottendog power supply, and a Kohout sound board while I take time reconditioning the original boards.
Oh yeah, and I'm nearly finished with my LED conversion, have a new speaker to install, and will be replacing the volume pot and ancient power cable.
If I ever stop tinkering with it, I'll put a sticker on the inside that says "Orbit complete!" with the date I finished the core reconditioning.
