Three days after putting everything up on gopher one of my co-workers came in with a tape from NCSA saying "hey. I got this interesting program from the NCSA guys. They call it a web browser."
(But early versions of mosaic and navigator understood Gopher URLs, so it wasn't a complete waste of time.)
There are some gopher diehards about. http://gopher.floodgap.com/gopher/gw . The relevant Wikipedia page says 'In February 2022 Veronica indexed 325 gopher servers.'
I remember the orange screens. And remember a "squash the bug" game possible due to the press-sensitive screen. But while I remember the admin mentioning some of PLATO's broader capabilities, that wasn't part of the student culture or knowledge base.
The local online community, for example, was based around the CONFER program running on the CDC Cyber, a machine accessible via several unlocked terminal rooms running dumb terminals.
I then went to UIUC (Illinois) for graduate school, in the physics department. PLATO was much more integrated into school life there. But this was also the time of Archie and Gopher, and of course the Mosaic web browser came out of UIUC shortly after I arrived. I only ever used PLATO as a T.A., to enter undergrad grades.
I mean sure. Except for those places, the only place you could find a multi-thousand dollar PLATO terminal was the old RF research building. And CDC headquarters and a one or two at Cray's lab.
