DigitalUniverseDemo ------------------- DESCRIPTION This is a demo version of the commercial software package "The Digital Universe". It has the following restrictions and limitations over the registered version: 1. Stars, galaxies, nebulae, and clusters are only shown in a square from 4 to 7 hours right ascension and -15 to 15 degrees declination. This roughly covers the region occupied by the constellation of Orion, and is visible from both the northern and southern hemispheres. 2. The demo version will not allow you to simulate a view of the night sky later than October 15, 1995. 3. Most of the hypertext encyclopedia of astronomy has been removed. The exceptions, which remain with this demo package include: - the online help on how to use the software - the description and pictures for the Sun - the description and pictures for M42 (The Great Orion Nebula), M43, M78, IC 434 (background illumination for the Horsehead Nebula), and Betelgeuse - objects which are located in the region defined by restriction # 1. For information on how to obtain a registered version of the software, as well as a fairly comprehensive list of the program's features, please see the accompanying file entitled "ProductInfo". In addition to removing these restriction, a 138-page user manual is provided, along with a version of the executable optimized for 68020+ CPUs without a math chip (the executables provided with this demo are compiled for 68000-based machines and 68020+ CPUs with a math chip). REQUIREMENTS This demo will run on any Amiga with Workbench 2.04 or greater, at least 3 megabytes of memory, and approximately 6 megabytes of hard drive space. Due to the calculation-intensive nature of this software, an accelerated Amiga and math chip (FPU) is strongly recommended, though not required. INSTALLATION The software is installed with Commodore's standard "Installer" utility, shipped with later Amigas. If you do not have this package, it can be obtained via the Internet on an Aminet FTP site (such as ftp.wustl.edu) in the "util/misc" directory, as "Installer-1.25.lzh". "The Digital Universe" requires MUI (Magic User Interface) 2.3 or later in order to operate. It can be obtained via the Internet on an Aminet ftp site (such as ftp.wustl.edu) in the "dev/gui" directory as "mui23usr.lha" and must be installed before attempting to use "The Digital Universe". Then, just click on the DUDemo-Install icon and answer the questions. You must do this even if you extracted the archive where you would like to use it. In that case, just select an "in-place" installation. RUNNING THE PROGRAM To run the program, just double-click on the "DUDemo" icon. On some Amigas with 3rd-party graphics boards, the introduction sequence *may* cause your computer to crash. If this is the case, or if you wish to bypass the introduction, click on the "DUDemoNoIntro" icon instead. If you wish assistance in using the software, a context-sensitive help system is built in. Just place the mouse pointer over the gadget or window you need help with and press the HELP key. If your mouse pointer is over the "backdrop" window (where the stars, etc. are drawn), general information about using the program is presented. QUESTIONS?
