So here I go into the world of classic arcade games..
Got a Missile Command of of CL...
The description from the previous owner was that they were playing it and it "just went out, could hear sound for a little while, then nothing"..
I have checked all of the fuses for continuity in the bottom of the cab and they test ok.
It does not boot or go into test mode. The monitor looks good and I can get Red Green or Blue solid my adjusting the cutoff dials on the back of the Yoke.
I am a newbie but ... so far I test from the harness ground to each of the test points good:
adjusted the crystal on the ARII and got these voltages to measure at PCB test points.
+5v is at 5.1 (somewhere on KLOV they said this was good)
+12 is at about 11.97
-5v is at -5.09
Edge connector is not perfect but I cleaned with an eraser and tested continuity from the harness ground to the PCB test points and they seem to work well.
I took the three large socketed chips removed them and cleaned the legs with an eraser, but maybe I need to get something better.
So what is the next step, do I need to search around for someone to test/repair my PCB? What else should I be testing? How do I test the ARII?
Any help would be much appreciated!!!
