Swapped in known working K1, no change.
Earth jacked up on splash screen.
No sprites in gameplay.

Can coinup and start game.
Cannot shoot (no shoot sound) and score does not go up.

Just getting into this one.

Any ideas ? Will look at repair logs and see what is supposed to get K1 started.

Saw that one already too.
 
Maybe some helpful info here:


Konami1 is a customized 6809 CPU, isn't it?
 
Wow. I'm spread way thinner than I thought lately.
I guess I already posted this.

😳🤷‍♂️

 
Now I can play the game with no sprites and run up the score. So it's "playing" but not displaying the sprites.

I am still getting "Konami 1 not responding" on bootup.
