The WD1003-RA2 is an IBM AT combination RLL hard disk / 2 floppy disk
controller card.  I believe that it supports a maximum of 1:2 interleave.
Here is some additional info:

wd1003-wa2	IBM AT combo MFM hard disk / 2 floppy disk controller
wd1003-wah	IBM AT MFM hard disk only controller

I believe that the WD1003-RA2 has been replaced by the WD1003V-MR2 and
WD1003V-SR2, but don't hold me to this.

You can probably get Western Digital to send you a data sheet by calling them
at (714) 863-0102.
