2500 SX/25 (250-1610) Features Faxback Doc. # 1122 The Tandy 2500 SX/25 delivers IBM PC/XT/AT compatibility in a high-performance environment. Featuring a 25 MHz 386SX microprocessor, this computer enables you to run popular software packages and to add industry-standard expansion options. Many advanced features are standard. Features and options are listed below: STANDARD FEATURES: 25 MHz 386SX Gives you 386SX processing power and a 32-bit CPU with a microprocessor 16-bit data path. Industry Standard- Ensures compatibility with hardware and software built to Architecture (ISA) IBM standard for PC/XT/AT. MS-DOS & OS2 Lets you choose the operating system that best supports Compatibility your software. 101-key enhanced Provides easy typing with a standard 101-key layout. keyboard Features auto-repeat to reduce the number of multiple keystrokes. High-capacity, Enables you to read and writer standard-density (720KB) and 3 1/2" diskette high-density (1.44MB), 3 1/2" diskettes. drive Three disk Enables you to install hard drives and diskette drives. drive bays Three 16-bit Permits installation of 16-bit adapters. These are full- standard sized (13") slots. Some 16-bit adapters use a higher data expansion slots transfer rate than 8-bit adapters. On-board VGA- All standard VGA, EGA, CGA, MDA and Hercules graphics modes compatible video are supported through an externally connected analog VGA monitor. Audio hardware Enables you to record, store, and play sophisticated music and sound. Includes an analog-to-digital/digital-to-analog converter, a built-in speaker, a digital volume control, a microphone connector, and a headphone connector. 2MB of dynamic, Enables you to run a variety of software. This memory is random access permanently installed on the main logic board. On-board memory (DRAM) sockets enable you to install additional memory. Built-in diskette Saves you the cost of a diskette controller board and the drive controller use of a 16-bit slot when you add diskette drives. Supports up to two diskette drives. Built-in 16-bit Enable you to quickly add convenient, reliable hard disk SmartDrive (IDE) storage. SmartDrives provide maximum performance at minimum connector and cost. The built-in controller supports up to two controller 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 Saves you the cost of a PS/2-style mouse board and the use port (mini-din of a 16-bit slot. connector) Built-in serial Saves you the cost of a serial expansion adapter and the port use of a 16-bit slot when you connect a serial mouse, and external modem, or other serial device. Built-in headphone Enable you to connect a microphone or a line-level audio and microphone input device. connectors Built-in parallel Saves you the cost of a parallel expansion adapter and the port 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 computer is internal clock turned off. The clock's battery also powers the CMOS RAM, which maintains current configuration settings. PS/2-style mouse Enables you to choose program and menu options quickly. Move the mouse to position the cursor and highlight our selection. Then, click the left mouse button. OPTIONS Additional Give you a variety of storage options, including: high- storage devices capacity and standard-capacity diskette drives (3 1/2" or 5 1/4"), internal hard disk drives (3 1/2" or 5 1/4"), and/or disk cartridge systems. Memory upgrade Contains 256KB or 1MB or 4MB SIMMs, rated at 70ns, to kit increase system memory on the main logic board or on a 16-bit memory expansion adapter. Video memory Increases the video memory on the main logic board from upgrade kit 256KB to 512KB, letting you use more Super VGA modes. 25 MHz 387SX Increases the numerical processing capability of your math coprocessor computer. A math coprocessor can process numeric data more quickly than the CPU. Modem Transmits and receives data through an ordinary telephone line. Digital scanner Converts printed text and graphics to a digital form. FAX adapter Transmits and receives scanned graphic images through a telephone line. CD-ROM drive Accesses the enormous storage capabilities of read-only disks. Multiple- Lets you use more Super VGA modes. Connect a multiple- frequency frequency monitor or 8514/A-compatible, multi-frequency monitor monitor. To use some Super VGA graphics modes, you must also install a video memory upgrade kit. IDE hard drive Install internal hard drives in the 3 1/2" bay, the 5 1/4" bay, or the expansion adapter area. The IDE hard drive connector in your computer supports up to two internal hard drives.
