We did something like that starting up our ISP with fiber installations. The whole village helped digging the trenches, pulling the fiber. The welding we got a little lesson on, and then had a few people doing the fiber welding all over the village with borrowed equipment. This was about 25 years ago, webserver was running on a then ancient 8086 (or 286?) running Linux :-)
Couldn’t have been anything older than a 386 as that was minimum spec even for Linux 1.0.
Seems I have the computers mixed up in my memory, it was definitely a IBM PS/2 Model 70 486. But our computer club were running some 8086 with a version of Linux before that as a router, think you had to compile the core yourself to get it working. Not to mention getting two different network cards running... My memory is fuzzy, wasn't me doing it, just watched the guy do it and bought him lunch :-)
