hi Phil,
Checking the NTE2016 data dosn't say its a high side driver.
On the point about how this worked before electronics - I think there has to be an elegant solution there.
I feel sure that the cams produced the 'code' for the 8 lamps.
Drop the inverters. There are 16 output combinations from the cam switches.
Regarding the number of switches, I'm wondering if the metal frame is the common of the 4 contact sets???
Look at my earlier EXAMP.pdf, it shows 4 switches driving the 8 lamps.
