Of course it can. Out on OpenBSD and fire up a light duty webserver. We did it plenty 25 years ago, it’ll still work today.

Using more advanced web stuff is the more interesting bit from his story.

My favorite web server I built with a 486dx2 running Tom’s Root Boot. I attached a 7 drive SCSI disk array of CD ROM drives. I’d then mount Linux install disks into the web server tree as an install mirror. The system had no writable media. The floppy would be set into read only mode and it had no installed hard drive. It was a RO webserver. If it was hacked I could just reboot.
