Yes, I remember taking a Fortran class there in 86 and using those terminals. The touchscreen felt like a plastic membrane over the glass, and gave a little wherever you touched it. What I remember most were the terminal keyboards. The keys were sprung like automotive suspensions, so you had to really hit each key with force to get it to register. When I got home after that quarter my dad yelled at me for pounding the keyboard at home - my typing habits had become almost violent.

I also recall seeing the Plato system being shown off in a display at the Worlds Fair in Knoxville in 1982. I took a peek at the Wikipedia entry for the fair, and it notes that several new technologies were debuted at the fair, include touch screens. Follow the link to touch screens and there's a picture of our friend, the Plato V.
