Depends on the schools for networks. I attended a college that finished adding wired networks to their dorms in 2000 or so. It just wasn't a campus priority in the 90s, fewer students had computers back then. If it was a school with more money or an engineering school they got to it earlier, the rest added it when they added it.

Also depends on the environment. My dad used to repair the pre-PC computers: Amiga, Commodore, Atari, Spectrum, etc. I've had access to them before many others have even seen a computer. I've been given a really heavy, not-completely-broken and usable laptop before they became affordable for normal people.

People who grew up with or lived in the tech environment had access to lots of things.

I was at an engineering school 90-93 (WPI) and they didn't have network access in the freshman dorms. Maybe they had it in the newer ones.
