As a one-time PLATO user (some employee training courses at CDC used
PLATO), I'm curious if the courseware/software and hardware still exists
for the host side of PLATO--and the amount of same.
In the day of the old plasma-display boxes, I believe that hosting was
done using Cyber 70 mainframes running KRONOS (or NOS if you're more
up-to-date).
