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)
3 1/2" diskette and 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
expansion slots data transfer rate than 8-bit adapters.
On-board VGA- All standard VGA, EGA, CGA, MDA and Hercules graphics
compatible video modes 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 a
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
drive controller the 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
connector and minimum 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
port (mini-din use 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
port 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 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 an
ordinary 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.
