1. Introduction
The NPC-486E is a fully functional and complete PC/AT style computer contained on a
single printed circuit board. All PC/AT subsystems are included and are 100% compatible
with the standard PC/AT architecture. The NPC-486E is guaranteed to run all PC/AT
compatible software.
The small form factor of the NPC-486E, 5.75" by 8", is achieved by using heavily
integrated chip sets and state-of-the-art surface mount manufacturing. The form factor
and mounting coincides with that of a standard 5.25" disk system.
The PC/AT subsystems normally found in a desktop unit are built in to the NPC-486E.
These systems include the CPU, system RAM, system ROM (BIOS), DMA, counters,
interrupt controllers, keyboard, and speaker of the motherboard; the floppy and IDE hard
disk interfaces of the disk controller; the serial ports COM1 and COM2; a parallel port,
LPT1; and a local-bus VGA display adapter capable of driving both flat-panels and CRTs.
Additional subsystems are integrated into the NPC-486E which further enhance its PC/AT
functionality. These include a PS/2 style mouse and a 16-bit Ethernet interface.
Special features and functions are included on the NPC-486E to address the needs of
embedded control. These functions include a watchdog timer, a solid state disk, and an
ISA bus extension based on the PC/104 standard.
