So the way Atari configured the Cockpit version of Star Wars to use both a 6100 or the 25" Amplifone was actually pretty smart.Yep. The datasheet already tells us that. But it's nice to see it molded into the jug. Congrats!
When are you doing the physical fit tests? Install the tube then reassemble all of the bezel and CP stuf that goes over it.
That's the problem with some tubes that are otherwise dropin replacements. They mount fine. But the CRT face is either too far away from the plexi or (worse) it's too close and you can't reassemble the game.
I really hope everything works mechanically!
The 6100 get's installed from within the inside of the cab where you sit to play the game. It sits flush to the back of the monitor shroud and smoked glass. It has to go through 2 wood frames that are just behind the glass so the fit is very tight. One wood frame is permamately attached to the cab while the other is removeable and is required to be removed when the Amplifone get's installed so that the Amp mounting brackets in the cab are exposed. It's a little difficult to describe it if you cant see it in person.
The 25" Amplifone mounts from the opposite side of the cab. It get's installed from the very front of the cabinet through the access door. The ears on the tube simply go over the 4 welded in bolts of the exposed mounting brackets inside of the cab and get bolted to it. There is quite a bit of space around the bolts so the shape of the ears should not make any difference in this particular cab but I could see where that could be an issue in other cabs. It's actually quite a simple install and much easier than the 6100. The Amp sits about 7" behind the smoked glass and once the 6100 wood frame is removed that exposes the metal mounting brackets, there is nothing directly in front or behind the AMP to interfere with it's installation. I assume Atari did it this way because the opening in the monitor shroud is only big enough to view a 19" monitor when it's sitting flush to the glass. As you know the AMP is 25" so you would lose a lot of the viewable tube if it was also mounted flush so Atari pushed it back about 7" to give you a 100% viewable 25" tube through an opening meant for a 19".
