There seems to be some basic setup information here — https://www.manualslib.com/manual/940845/First-Data-Fd100.html#manual — but it’s thin on hardware specs and long on “congratulations, you can scan credit cards now!”

The firstdata site (https://www.firstdata.com) seeeeeems to be steering people towards cloud-hosted services, and doesn’t provide much detailed information about the terminal hardware, but their service/support section might be a good place to dig around?

Okay so I have ended up in the possession of a FirstData FD-100 credit
card terminal, and I have been trying to figure out how one would, or if
it would even be possible to, connect it to a computer or raspberry pi
and print arbitrary things with its thermal printer and maybe even
receive input from the keypad. I have so far turned up very little
information, though my information-gathering skills are not too great.

Has anyone maybe got any ideas?
