The TNFS protocol used by FujiNet has also been used in other network cards for old 8-bit computers. My own ZX Spectrum is fitted with a Spectranet card which enables the same kind of connectivity and creativity. I wrote about it in my "DevOps For The Sinclair Spectrum" article[1] which featured here, and my TNFS site is now available through a JS emulator on a web page[2] if you want to see the kind of thing you can create. It's sort of like an old-school BBS, except the code is downloaded and run directly on your computer, which opens up a world of possibilities like multi-player games and even bridges to protocols like Gopher, Gemini and IRC which make communicating with the "modern" Internet possible even on an ancient tape-loading 8-bit micro from the 80s. Really fun stuff!

I’m still not quite sure what FujiNet is and how it is the last peripheral for your vintage devices. Gives me Zombo.com vibes.

What a fun project! I think if I ever get around to opening my own makerspace/cafe, I'd like to have something like this running in the lobby for people to see how early computers looked and worked while still being somewhat useful with fujinet.
