I've just acquired my Tommy and it came without 'Blinders' or 'Arches' fitted. In fact not even the servo driver board. After Googling and asking on forums I found Mark's article.
I ordered a new set of his repro Blinders which arrived very well packed and looked terrific! His help and advice invaluable. He continued to follow up on my project.
I received the new Drive board made by Frank at TNT in the USA. Plugged everything in and powered up. After hunting through the menu and finding a 'Disable' feature for the Blinders in the Adjustments section, everything suddenly sprung into life!!
My machine now looks and plays exactly how it was supposed to. It would never have done without the help of Mark (Bakerman) and Frank at TNT Amusements.
Highly recommended!!!
