Schematic Question - Pin 5

[jdduffield]

Having trouble reading this schematic. What is going on with pin 5 here? (Muroidea circuit)

Is it going nowhere?

 

[Harry Klippton]

The LM308 datasheet says pin 5 has no connection

 

[Chuck D. Bones]

Robert does that just to mess with our minds.

That little square looks so innocent doesn't it? It's a portal. That's all I can say.
