NEW DIGITAL RESEARCH MULTIUSER DOS OFFERS COST-EFFECTIVE ALTERNATIVE TO UNIX, LANs MONTEREY, CA, --Digital Research Inc. recently announced Digital Research Multiuser DOS, a new multiuser, multitasking operating system. The product offers a cost-effective alternative to other multiuser operating systems such as UNIX and Xenix, as well as to local area networks. DR Multiuser DOS replaces Digital Research's Concurrent DOS 386 and incorporates technology from that product and from DR DOS 5.0. The new product reflects Digital Research's position as the premier vendor of PC-based DOS operating systems. DR Multiuser DOS enables a single 386SX, 386 or 486-based computer to host multiple DOS applications and multiple multitasking users on terminals and PCs linked through a standard serial port connection. The operating system provides the advantages of a LAN at a fraction of the cost, with installation and ongoing administration both greatly simplified. "For small, transaction-oriented workgroups and file-intensive applications, DR Multiuser DOS is the most effective, economical solution on the market," said Dick Williams, Digital Research president and CEO. "A 10-user system, for example, could save a company more than 50 percent of a LAN's hardware costs." Unlike multiuser UNIX platforms, DR Multiuser DOS enables businesses to retain their investment in standard DOS application packages, such as accounting, database management, spreadsheets and word processing, while providing a productive workgroup environment for sharing information and hardware resources. High-performance, multiple sessions DR Multiuser DOS supports a wide variety of terminals, as well as PCs running an emulation program included with the package. The number of users supported is limited only by the number of ports available and the need to maintain an adequate response time--up to a maximum of 64 users. Maximum performance is attained through the use of disk caching and a technique called (Dynamic) Idle Detection System (patent pending), which ensures that idle tasks do not tie up the processor. The facility can even free the CPU between a user's keystrokes. DR Multiuser DOS can support three users simply by connecting terminals to the standard COM1 and COM2 ports, or 10 users using the default menu selections for several popular 8-port serial multiport cards. The operating system also includes drivers for 8-port and 16-port intelligent cards and can support drivers for cards with up to 64 ports. The new operating system supports color text and CGA graphics on connected terminals and PCs that support color graphics. It offers a robust security facility, with the option to enforce user passwords and secure disk media. Users can access CD-ROM devices, making DR Multiuser DOS the most cost-effective multiuser data retrieval system available. DR Multiuser DOS uses sophisticated memory management techniques, based on technology developed for Digital Research Concurrent DOS 386 and DR DOS 5.0, to move most of the operating system, resident programs, and device drivers out of the 640K memory region. As a result, more than 570K of memory is available to each DOS application. The operating system supports up to eight sessions on every console. Each session is independent of the others--a user can even reboot (using CTR-ALT-DEL) without affecting the other sessions. All sessions support graphics mode on the host PC console. On connected color terminals or PCs with color monitors, this feature can be used for text-based applications that have a graphics component--such as the page previewer in WordPerfect or the graphics display within Lotus 1-2-3. All sessions can also share the same mouse, with the pointer position maintained on each. Price/Availability: DR Multiuser DOS is priced at $695, and is available now. Further information is available from Customer Services Dept. at (800) 443-4200. Founded in 1976, Digital Research Inc. markets and develops a complete line of general-purpose operating systems for microcomputers, including DR DOS 5.0 for IBM and compatible PCs, FlexOS, an industry-leading real-time protected mode operating system, and DR Multiuser DOS, a multiuser, multitasking operating system, as well as a line of graphics systems and application software for business and professional use. Headquartered in Monterey, CA, the company's worldwide locations include the United Kingdom, Germany, France, Japan and the Pacific Rim. DR DOS is a trademark of Digital Research Incorporated.
