Tech Tangents II | Tiny Pentium's New Mechanical Keyboard and Mouse @techtangentsii | Uploaded April 2021 | Updated October 2024, 1 hour ago.
I picked up a set of Cherry peripherals for my Tiny Pentium and they are fantastic. I don't think I can do better than these given their size.

If you also want to grab either of these here are some links to them on ebay that will help me out if you get one:
