Cinematronics arcade italian clones repair. Pt. 3: Skyfire lives again!

This is the third video of a (long) repair session of three Cinematronics black'n'white vector arcade games. The clones were made in Italy by a company called "Microhard". In this video I show the repair of the first (and the only easy) boardset of the three I got for service.
This game is a clone of Cinematronics' Tailgunner.
