Quoted from herg:Finally, I have one in my Tron (Pro), and it's very close to finished. I have not yet looked into the list of other Stern machines that this will support. It certainly will NOT be useful with the newer machines that have LED boards with serial control, but I believe it will work with the rest.
Great news, sir. If it supports TRON, it should support any SAM game going back to WPT (the first SAM game save for a few Sopranos) not counting games with LEDs already as you noted.
