Sorry, the image was not showing.... what's going on with those 2 diodes and pull up, so there's always 9v high ... I would presume either not both but either of the diodes would pull it ground? not both like an AND logic calculation
Which came first, diode logic or relay logic?
I cant see what your talking about butif 4 or 5 is low, then current is sinked thus logic = lowif both are high then current sinks though 1, thus logic = high
