Chicago Cubs 'Triple Play'
Gottlieb, 1985Probably a stupid question, but can anyone show me the grounding point for a Gottlieb System 80B alpha numeric display board (20 characters-MA644)? I have added grounds to all of the other boards, but due to my deficiency in reading schematics, I am not sure where to attach a ground. I haven’t found an answer on PInwilki or other internet sites. Do people ground the display? If so, can anyone can share/suggest the location to attach a ground to the display?
Thanks,
Phil
In research and dealing with upgrades to my two system 80B games (Genesis & TX Sector) there was no indication or recommendation of display ground mod that I am aware of. A repeat concern or suggestions I saw regarding the display was ribbon cable and circuit board condition and connection.
Thank you rgb635 for your reply , I glad you had the same results that I have had when searching for information on grounding the boards including the display board. I was afraid that I was overlooking something obvious.
