Only 75 s is required to read 128 digital input pins and to write to 128 output pins.
This transient immediately triggers a timer whose output pin 3 goes positive, turning on transistors Q2 and Q3.
It is similar to the operational amplifier, but also has differential output pins.
When it finishes, the result is placed on the output pin.
It still has separated video output pins, and the separated sync pin is now gone.
The left hand column corresponds to the left-most flip-flop's output pin, and so on.
This is because rotating the output pins will not rotate the cycloidal disc in the correct way.
Likewise the output could be tied to a logical 0 to model the behavior of a defective circuit that cannot switch its output pin.
With a large number of test chains, not all the outputs can be sent to the output pins.
The load capacity of each output pin was sufficient for one TTL input.
