Western Digital WDAT-140 Manual

Introduction
Western Digital manufactures three AT adapter boards for use
with intelligent or integrated hard disk drives. These drives have their
own controller electronics mounted directly on the drive assembly.
Many AT systems require an adapter card in order to accommodate these
drives. The WD-AT adapter boards all provide an integrated hard disk
interface that sup-ports two daisy chained drives. The WDAT-240 and
WDAT-440 also provide a floppy controller which can support two daisy
chained floppy drives. Two serial interfaces and a parallel interface are
available on the WDAT-440.

Unpacking The Adapter Board
Hold the adapter board by the ends. Static electrical
discharge can permanently damage components if the
board is not carefully handled.
Remove the board from its anti-static pouch and inspect it for any
visible signs of damage (scratches,
connectors). Contact the dealer if there is damage.
Retain any packing materials for reuse if it becomes necessary to
return your WDAT board.
