PLATO Terminal Emulator

You will need to download and install a program to get on Cyber1. We call this program Pterm. The original PLATO terminals were of several types, a "dumb" terminal by Magnavox (commonly called a Maggie) which had the orange gas plasma display, a more advanced terminal called the Plato V (also called a PPT), the Information System Terminal (IST) series (IST-I, II, and III) that used a black and white CRT, and the CDC 721 (also called a Viking) that was also a CRT but with a slow green phosphor display.

These are not the only terminals that were used to access PLATO, but they are the most common of the original equipment.
Our terminal emulator is based on the model of the Plato V (PPT), and includes emulation of the Intel 8080 micro-processor. We also support a hybrid color terminal which could be considered to be a color Plato V. Color is only available under the ASCII port 8005 when connecting, but it achieves faster perceived output due to buffering design at the mainframe.
