The Canadian city of Toronto plays host to the second Multi-User Computer Show on May 17, 18 and 19 this week, combining both the Unix and Comgraph events that were held separately before last year. Over 14,000 delegates are expected at the Metro Toronto Convention Centre where 250 companies will be represented. The Comgraph side of the show is sponsored by the Electronic Desktop Publishing Association, the Unix part by /usr/group/cdn, the Canadian Unix users group. The latter has organised a series of lectures, discussions and technical tutorials running parallel to the show, keynote speeches are being given by Gilbert Williamson, president of NCR Corp, and Nicholas Donofrio, president of IBM’s Advanced Workstations Division. Waterloo, Ontario-based Wollongong Group is to set up a network for the duration of the show, during which AT&T will be demonstrating a new release of Topaz, its three-dimensional imaging system for personal computers, and Nu-Vista, a new graphics card for Macintoshes. Apple will be demonstrating Visionary, a new front end film producer on the Mac II, Hewlett Packard is set to make some announcements in the graphics environment, and Xerox will be showing off its new 4650 printer and Professional Illustrator for workstation design artists. The Comgraph conference will be addressed by Adobe Systems president John Warnock and Steve Roth, editor of US desktop publishing magazine Personal Publisher.
