How much more would it cost for unit that has 63 or more inputs?

Thank you. The display just needs to display "1", "2", etc. My colleague was interested in one that had 63 inputs or more. He also mentioned a Raspberry Pi. Unfortunately, I'm not familiar with either the Arduino or Raspberry Pi units.

I currently have a LED box that I used to test continuity on a 28 pin circular connector. See attached photo. Pin 1 when probed (probe is attached to box) on the circular connector corresponds to LED 1, etc. I would like to make a digital display version of this. Any help appreciated on components needed, circuit examples, etc.
