4900 with all green screen
« on: March 08, 2006, 12:14:55 am »
This 4900, 4700, whatever (it's not a GO-7) came in my tron.  The board is working with game sounds but all I get on the monitor is the green gun painting the entire screen.  I have no schematics to work with and before I put a cap kit into it I want to see some kind of representation of the game playing.  Anyone have suggestions on where to start with this beast?

If you can dig up another monitor, hook it up to the output and see if it's actually outputing what it should. 

*Just* green, eh?  Got a picture?

It's probably a 4900 Wells-Gardner. You can get the manual from either www.arcadehelp.com (the Spies Archive) or www.atarijeff.com (files section).
