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.
