I have an atari avalanche that is kinda playing blind. I can coin it up and you can hear the game sounds in the background but all I get on the screen is scrolling raster lines. The monitor is a black and white motorola xm701-10 and ideaas where to start? I have never worked on a monitor this old
 
Very cool looking game! Did you recap the monitor? This may sound dumb but check the connector to the PCB make sure they are making good contact. The Bagman i got today was playing blind that thats all it was ;)

Good luck buddy,

Braido...

Ps. let's see a picture of that game.
 
Hey Braido,

Haven't recapped the monitor, I have been focused on getting the pcb up and running so now that the pcb is working I am going to dive into the monitor which should be interesting because it is so old. I'll try to get some pics up of the game.
