This rugged, high quality meet the size, power consumption, temperature single-board system contains all the component range, quality, and reliability demands of subsystems of a PC/AT motherboard plus the embedded applications. equivalent of six PC/AT expansion cards. Among the many embedded-PC enhancements Key functions included on the Little Board/486i that ensure fail-safe embedded system are a 3.3V CPU, DRAM, embedded-PC BIOS, operation are a watchdog timer, a powerfail keyboard and speaker interfaces, four buffered NMI generator, and an onboard bootable Solid serial ports, IEEE-1284 enhanced parallel port, State Disk (SSD) capability. System operation floppy and fast IDE drive controllers, an LCD/CRT requires a single +5V power source and offers local bus display interface, a SCSI-II bus, and an “green PC” power-saving modes under support Ethernet LAN interface. In addition, the of special Advanced Power Management (APM) Little Board/486i includes a comprehensive BIOS functions. Ampro Computers, Inc. • 4757 Hellyer Ave., San Jose, CA 95138 • Tel.
