Centipede experts, please help!
« on: November 08, 2007, 09:16:42 pm »
Okay, so my Centipede has a hunger for monitors. It has eaten a flyback and a green signal IC on the two monitors I've given it.  I need to step back and have some other opinions on this.

I have documented all of the voltages from the test points below.  The game is still playing, the graphics are intact and the sounds are working.  It still coins up and has an attract mode.

ARII TEST POINTS
36VAC     17.8
36VAC     17.8
-5VDC     -4.8
+12VDC   11.8
+10.3VDC UNREG     13.6
+22VDC   25.0
-22VDC     -24.8

GAME PCB
-30V     -26.2
+15V     14.6
-22V     -24.8
+22V     24.7
+5V     4.9
-5V     -4.8
+12V     11.8

GAME PCB CONNECTOR (THE LARGER ONE)

GND
12.8

-25.0

Nothing is like stepping back, looking at your games, and thinking 'wow, I've done this, and I have these!'
