AMPRO LB3-486-Q-77 CPU Boards-Series Little Board/486i AMD 486DX/DX5, 66 or 100/133MHZ with SDRAM, VGA CRT/LCD/EL, LAN, SCSI-II, 4x Serial, Parallel, P/C 104, DiskOnChip 2000 Simple Type: CPU Boards

The Little Board/486i is an exceptionally high integration, high performance, 486DX-based PC/AT compatible system, in the footprint of a 5-1/4 inch disk drive. This rugged, high quality single-board system contains all the component subsystems of a PC/AT motherboard plus the equivalent of six PC/AT expansion cards. Key functions included on the Little Board/486i are a 3.3V CPU, DRAM, embedded-PC BIOS,keyboard and speaker interfaces, four buffered serial ports, IEEE-1284 enhanced parallel port, floppy and fast IDE drive controllers, an LCD/CRT local bus display interface, a SCSI-II bus, and an Ethernet LAN interface. In addition, the Little Board/486i includes a comprehensive set of embedded system extensions and enhancements, plus it is designed to meet the size, power consumption, temperature range, quality, and reliability demands of embedded applications. Among the many embedded-PC enhancements that ensure fail-safe embedded system operation are a watchdog timer, a power fail NMI generator, and an onboard bootable Solid State Disk (SSD) capability. System operation requires a single +5V power source and offers “green PC” power-saving modes under support of special Advanced Power Management (APM) BIOS functions.
