    Well hello all So this has come to some conclusion My friend socketed the IC's the snap clicks on to for extra height The ROMinmator is directly on the board with pins, no ROM socket Now it fits with Kero's rominator But, i cannot start from a 6.0.8 system anymore;) Not from ROMinator, also...

    Building an internal grayscale card for the SE/30
