#DIFFERENCES BETWEEN XTERM AND PTERM HOW TO#
Anyone who has a working PLATO terminal is invited to contact us for information on how to get your terminal connected to Cyber1. Some additional terminals were donatd by Aaron Woolfson to the Living Computer Museum in Seattle, where they do have a PPT on display for public access.
A demonstration "classroom" was setup at the Computer History Museum for the conference held in 2010 (please see the links at the top of the page for photos). Due primarily to the efforts of one of our users - Aaron Woolfson - and drawing on the technical and social resources of the PLATO community, a small number of original PLATO terminals have been restored to working order and can connect to Cyber1 still today. I have a real PLATO terminal (Maggie, Plato V, IST-I / II / III), and it powers up. Note that port 8005 achieves faster perceived output For the most feature-richĮxperience connect on ASCII port 8005, for "classic" protocol connect on port 5004. Think of Pterm up to version 5.0.9 as a hybrid color PPT, and versions 6.0 and newer as a hybrid color IST-III. There were manyĮxperimental terminals for early development of color displays and other hardware platforms. These are not the only terminals that were used to access PLATO, but they are the most common of the original equipment. Using a faster Z80 processor with bank switchable RAM for larger resident programs, a green phosphor CRT, and separate keyboard, this was designed for both PLATO and other tasks. These terminals were designed as a single unit with integrated keyboard and used a Z80 and a RAM resident (downloaded from mainframe or loaded from flexible disk system). Using an 8080 processor it closely mimicked the PPT but used a CRT. Designed by CDC, there are three major subtypes. It featured natural wood sidings for display case and its separate keyboard. This terminal the pinnacle of original PLATO terminal design. This is an "intelligent" plasma terminal by Carroll which used a ROM "resident" for I/O featuring an 8080 processor. This is a "dumb" terminal by Magnavox which had the classic orange gas plasma display, a separate cabled keyboard, and usedĭedicated circuitry to provide the basic input and output for PLATO operations. The original PLATO terminals were of several types:
