Texas Nuclear I/O Board 885740 -- What is it used for?

[MathematicalPhysicist]

I read that this I/O board is for WSD scale, what is that?

I searched in google for WSD scale got something that got to do with librarians, so I assume that it's off track; so what is its usage?

First off, it is an IO board for a Texas Nuclear Computer

It is for controlling a Weigh Scale Dispense System
