I am trying to help one of my instructors figure out what the pinout of this device is and/or if there's a datasheet out there (I'm having a hard time trying to figure this out). Maybe someone has used one like this before? If so could someone steer me in the right direction or help me out here?
And what are all those little black boxes that appear etched into the PCB?
Well I guess I have an art project on my hands now

They're revealing your (lack of) age They used to be seen on just about every thick film hybrid circuit (when not covered in "paint") and they are simply "painted on" resistors. Sometimes they even had cuts for trimming (probably not by LASER though, at least not the early ones).
hmmmm I googled around but couldn't find more info on this . . .
[...] so this PCB tech is circa 80's maybe?
