question about outdated (?) technology - seeking advice

2. Take a picture and save it to your computer

Find wherever you stored it on your computer, then right-click and “Open with”, then select Google Chrome.

Once it’s visible on Google Chrome, right-click again and select “Search image with Google Lens” (or similar, it’s the last of multiple options).

What comes up will let you know if there’s any value to what you have, or at least let you know if it can still be used by someone.

This assumes you have a smartphone and know how to get images from that copied into your computer, which has to be Windows-based (since that’s all I know for providing advice).

Honestly, if you have a foot-operated device that was used to control a word processing program, you can just throw that out - there’s won’t be any current or future use for that kind of hardware, and I’m certain of that. But the docking station might work with certain current computers. However, if it does, it will almost certainly be a very specific subset.
