Quoted from Atari_Daze:Anyone have suggestions what other chips could be the cause of having most of the CPU controlled lamps fail to illuminate?
Check phase A, B,. For Bights it is phase C, D,.
Check continuity from the power supply to the playfield
Quoted from PM_Jeremy:Would a logic probe be useful for troubleshooting this issue?
For the IC part on the CPU board, a logic probe is great. Also, the game schematics would help in identifying what is going on. Remember two lamps are driven by one SCR.
Quoted from Atari_Daze:replacement spring steel for the upper playfield ramps
Where did you get the blue steel ramp flaps from? or did you make them?
If you made them, what did you use to cut the material?
Quoted from Atari_Daze:The steel ramp flaps were made from spring steel purchased from Marco. I used the broken flaps as a template, cut the steel with tin snips and then used a grinding wheel to remove burrs and round the edges. The lower flap on the right ramp was modified slightly to be wider than the oem piece in order to reduce the amount of gap next to the ball guide.
Thanks! Great job!
Quoted from Atari_Daze:The machine was missing a couple and when the new ones arrived, I realized how faded and tired the old ones looked
The star post from that area is lite blue. I had bought new ones
back in the day(1982's). The remake are darker to be more like
Williams/Stern.
