Nah. 83 is much too early for everyone having a pc in the dorm room, and well after 1993 for dorms often not having network.

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.
