Hi, Mike!

Have you checked out irata.online or cyber1.org? Both are running CDC Cyber
emulators to make PLATO available again. A special comm program (or, I
suppose, a PLATO IV terminal) is required, but the Windows/Mac/Linux clients
are available at both sites. Cyber1.org tends to focus on the history of
Plato, while irata.online tends to lean towards new development and
microcomputer access, with Atari, Apple, TI-99/4A, Commodore, and other
clients available for download.
