TANDY 2500 RSX (250-1620/1621) Features Faxback Doc. # 1897 * 25 MHz 386SX Gives you 386SX processing power and a 32-bit CPU microprocessor: with a 16-bit data path. * Industry-Standard Ensures compatibility with hardware and software Architecture (ISA): built to the IBM standard for PC/XT/AT. * MS-DOS and OS/2 Lets you choose the operating system that best compatibility: supports your software. * DeskMate/MS-DOS: Provided on diskettes to help you perform various tasks with your computer. The DeskMate graphical environment includes word processing, spreadsheet, filing, and telecommunications applications. MS-DOS 5.0 includes on-line help for all MS-DOS commands. * 101-key enhanced Provides easy typing with a standard 101-key keyboard: layout. Features auto-repeat to reduce the number of multiple keystrokes. * High-capacity, 3 1/2" Enables you to read and write standard-density diskette drive: (720KB) and high-density (1.44MB), 3 1/2" diskettes. * Three disk drive Enable you to install hard drives and diskette bays: drives. * Three 16-bit standard Permit installation of 16-bit adapters. These are expansion slots: full-sized (13") slots. Some 16-bit adapters use a higher data transfer rate than 8-bit adapters. * On-board VGA- All standard VGA,EGA,CGA,MDA, and Hercules compatible video: graphics modes are supported through an externally connected analog VGA monitor. * Volume control: Lets you adjust the level of sound emitted from the internal speaker. The volume control is located on the back of the computer near the serial port. * 1MB of dynamic, Enables you to run a variety of software. This random access memory is permanently installed on the main logic memory (DRAM): board. On-board sockets enable you to install additional memory. * Built-in diskette Saves you the cost of a diskette controller board drive controller: and the use of a 16-bit slot when you add diskette drives. Supports up to three diskette drives. * Built-in 16-bit Enable you to quickly add convenient, reliable SmartDrive (IDE) hard disk storage. SmartDrives provide maximum connector and performance at a minimum cost. The built-in controller: controller supports up to two SmartDrives. * Setup in ROM: Enables you to run the setup utility to update the computer configuration without accessing files on a diskette. * Built-in mouse port Saves you the cost of a serial expansion adapter (mini-DIN connector): and the use of a 16-bit slot when you add a PS/2-style mouse. * Built-in serial port: Saves you the cost of a mouse board and the use of a 16-bit slot when you connect a serial mouse, an external modem, or other serial device. * Built-in parallel Saves you the cost of a parallel expansion adapter port: and the use of a 16-bit slot when you connect a parallel printer or other parallel device. * Battery-backed Maintains the system date and time when the internal clock: computer is turned off. The clock's battery also powers the CMOS RAM, which maintains current configuration settings. (/tmc-08/30/95)
