This prototype, running on an Illiac-I, became PLATO. To see if Don could quickly come up with a prototype that could serveĪs proof-of-concept. The director at the time, Daniel Alpert, got together with Donald Bitzer Was concluded that computer-based education should not be pursued. The idea was first discussed at the University in 1959, inĪ long series of meetings led by Chalmers Sherwin. World's first computer-based community, PLATO.Įducational system created at the University of Illinois Control Systems pdf), a software emulationĬ is a group of people dedicated to the preservation of the The CDC mainframe operating system, generously contributed by BTĬonsulting & Systems Integration Services (formerly Syntegra). With PLATO, CYBIS, or early NovaNET, cyber1 will feel like coming home Total registered users = 5727, total signons = 6463.Ĭyber1 is the name for our mainframe-based CYBIS system. 4:44pm PST: REaltime has been caught up now, and all conenctions, Classic and ASCII are working. Also, if you login via Classic you may note that the clock is running very fast - this occurs when the system is down for an extended time, it is basically catching up from the last up moment - this also occurs when we adjust time for daylight savings. This is also the reason the status updates are not occurring and why the 'UNCERTAIN' message is shown. 6:59pm PST: Operator is out of town on business and will return today and figure out the issue. It bounced once earlier today, then went down and has not come up. 10:31pm PST: Unknown at this time why Cyber1 is down. 11 users currently signed on.Ĭyber1 sends a status update every 5 minutes to the website, and the last update was received 1 minute ago.

Contact Jeffrey Mortimore, Discovery Services Librarian, for help selecting file formats and with file conversion. The library recommends that researchers depositing works in Digital Commons, OpenICPSR, or any other repository, submit file formats in column A if at all possible, and consider converting file formats with a lower probability of long-term preservation to formats with a higher probability. Formats in column B are preferred over those in column C however, the likelihood of their long-term preservation is not as high as for those in column A. Those in column C have a lower probability. Those formats in column A exhibit the characteristics above and thus have a higher probability of long-term preservation. The likelihood of long-term preservation of content and functionality is higher when submitted formats possess the following characteristics:īelow is a table of file formats organized by probability of long-term preservation of content and functionality. Contact Jeffrey Mortimore, Discovery Services Librarian, for help selecting an appropriate repository and preparing your data for deposit. This is especially important for non-text formats, including images, audio and video files, spreadsheets and databases, and software.įor more information about curating your data, see our guide to curating and sharing data. While most repositories, including Digital Commons Georgia Southern, take reasonable measures to preserve this content and functionality, the best way to ensure that your file content will retain its use and value over time is to prepare and deposit file formats with the highest probability of long-term preservation. Given the current pace of change in digital technology, the long-term preservation of the complete content and original functionality (e.g., “look and feel”) of certain file formats may not be practical or possible.
