System FEATURES
Open Hardware and Software Architecture
• Designed for digital communications or as a freestanding general-purpose
processor for embedded applications.
• Single Board Computer with DOS and Utilities
• BIOS and DOS Bootable from Flash Memory.
• 25 MHz Intel 386EX processor.
• Runs 16 or 32 bit applications.
• In-place 512K upgradable Flash Memory for storing resident applications.
• DRAM expandable to 16 M using standard 72-pin SIMMs.
• PC-104 socket allows for a range of expansion options.
