Non Standard Logics SA, the Paris-based user interface specialist, has come up with software for X Window System developers to use and create demonstration versions of their programs. Called XDemoMaker and XDemoPlayer, the two-program set uses Motif, but the demos produced are independent of the user-interface and run under any X-terminal interface used with the application. XDemoMaker, which costs $6,000 in single units, includes editing and text-writing facilities. XDemoPlayer is licensed to XDemoMaker buyers along with unlimited copying rights for $4,000 for the first hardware environment, less for additional ones. Workstations currently supported include those from IBM Corp, Digital Eqipment Corp, Sun Microsystems Inc and Hewlett-Packard Co.
