INTRODUCTION 1

INTRODUCTION SECTION 1

The TEK-AT2 is a high performance PC/AT type

computer on a half-card format (7" x 4.7"). It

integrates all the basic functions available on an IBM

AT - like a hard disk interface and a floppy disk

controller.

Best of all, the TEK-AT2 is designed to operate in

environments where a sturdy and compact system is

essential. So elements such as a watchdog timer, solid

state disks, and a power failure detector were added to

make the TEK-AT2 perform even in the most extreme

industrial applications.

Built using CMOS technology, the TEK-AT2

consumes very little power. Typically, less than 7.5

watts. The TEK-AT2 is also a versatile board. It can

be installed in a PC passive backplane or, because of its

small size, it can be used as a stand-alone controller by

utilizing the four standard mounting holes and separate

power connector.

And to top it off, an XT expansion header

accommodates TEKNOR's TEK-PG VGA LCD/EL

series of display controllers or other optional expansion

cards.
