Chapter 3  The Engine of the PPC-L106T 
(PCM-9679)
3.1  Introduction
The PCM-9679 is a highly reliable single board computer based on the 
AMD LX800 CPU.  It offers built-in functionality comparable to a com-
plete industrial PC system, including a VGA/LCD controller, network 
communications, CompactFlash disk in a small 8" x 5.75" form factor.
For maximum performance, the PPC-L106T also supports a DDR 
SODIMM socket that can accept up to 1024 MB memory. On-board fea-
tures include an Ethernet interface, audio interface, socket for Compact-
Flash card, Enhanced IDE interface that supports the Ultra DMA 
protocol, one parallel port, four serial ports (RS-232 and RS-232/422/
485) with DB-9 connectors, and a mini-DIN PS/2 keyboard/mouse inter-
face. An SVGA/LCD display controller (for LCD and CRT displays) 
allows LCD screen resolutions up to 800 x 600 @ 256 K colors.
The PCM-9679 complies with the "Green Function" standard and sup-
ports three types of power saving features: Normal, Doze and Sleep 
modes.
The display type configuration is done through software. A single Flash 
chip holds the system BIOS and the VGA BIOS. This minimizes the 
number of chips and eases configuration. You can change the display 
BIOS simply by programming the Flash chip.
Flash memory also offers faster data access and longer MTBF than 
mechanical disk drives and is an ideal solution for critical commercial or 
industrial applications. The watchdog timer ensures the system will be 
reset if it stops due to a program bug or EMI problem.
