+OK.  I'm looking at the signals now...
+
+First, processor at 11A:
+
+pin 3 (IRQ line): Pulses vary in duration, making it somewhat difficult to
+determine frequency, but it's about 60 Hz (around 16 -17ms per pulse, 60Hz
+would be 16.6ms, I think)  This seems to be tied to the sound processor?
+(pulses get real short when no sounds are playing)
+
+pin 35: approx 650 ns/cycle  = 1.538 MHz
+
+pin 34: same as 35 (1.538 Mhz)
+
+Processor at 9A:
+
+Pin 3: Same as 11A (looks like 60Hz to me)
+
+Pin 35: Same as other processor (1.538 MHz)
+
+pin 34: Same as other processor (1.538 MHz)
+
+Hope this helps! ;)
