Hello, My name is James and I live in Lansing Michigan. I have a sit down version of f-15 that has a Zenith 25k8102 monitor in it that doesnt warm up. I took it to Tv store and they said that even if they had schematics the Zenith Sets were known to only last around 7 years. The neck of the tube doesn't warm up orange and he said that it what usually goes.
I looked up some specs in the IAM and see someone says it is 576 pixels and 57.00 refresh. Is that considered normal or a problem?
I bought one of those converter boards that goes CGA to VGA but it isn't working in this application. I was excited to find this site and read all I could in order to save this game. With great anticipation I recieved the CGA/VGA board in the mail. I installed it as per instructions but still have an extra wire. Occasionally on the LCD monitor coming out of the board I can get the screen to show the game screens but always rolling around and moving so I wonder if there is something about the sync in these games being unique.
What I would like to do is get this running and not have to spend another 3 days second guessing everything. This game was all torn apart but I got it so it accepts coins, fires rockets,chafe and joystick runs. I got all the wires put together and even made it to the 2nd level without the monitor working. Now if I could only figure out what I NEED to do to make it work so I could SEE the game when I am playing it. I think this game is kinda rare and hate to switch it to a computer case that plays microsoft flight simulator.
The monitor had a 10 pin plug in this order as good as I can figure.
10-red
9-Green
8-Blue
7-RGrnd,GGrnd,BGrd linked together on a black wire
6 empty
5 empty
4 empty
3-Black wire on schematic going to pin 1 which doesn't even show a wire there so what do I do with this? It is unattatched right now.
2-Vert Sync
1-Horiz Sync
so is ground the 7th wire? Is it grounded somehow special I don't understand on 3rd??
Number 5 wire is obviously coming and going somewhere. There are other holes in the plastic plug without wires so why is 5 there?
I wish I knew more, I hitched the combined Rgrnd,Ggrd,Bgrd as negative on the converter board. I used the converter board output to try a LCD monitor and an old computer moniter. It occasionally flashes distorted images of the game in play so I think that either the vga monitor or board isn't syncing or the scan is wrong, but at least the game is trying to put out video images. Anyone who can help me? Do I have to go to a tube or does someone have a used on that would work?
I think it is really cool to find this forum. Especially cool to find some other people with F-15 Strike Eagle Arcades !

....it shows the video connections. I would appreciate it if someone could tell me if the 3 wires linked together are to a ground. Since the monitor is out I don't have the BIG transformer installed that looked like it was for the monitor setup. Do I need it? The wires are numbered different but it still makes me wonder what is the black wire on the schematic that comes out number one pin and ends up the black wire on the molex position 3 wire? Is there another sync? Is there a special ground ? I am stuck !
