  Any one have copies of the WD controller
specifications for the
 PC/AT?? It would be a WD1003 model probably the -WAH version but any
 version would be appreciated.  The following is a list of some known
 versions  
 Tom, I'm not certain what you're looking for, but I've got the 25-30
 page booklets for both the WD1003V-SR1/SR2 and the WD1003V-SM1/SM2,
 if that's what you're looking for.  The chip lineup is:

 WD42C22
 WD1017
 WD10C22
 WD37C65 (for the floppy versions)

 Also have the databooks for the WD1007 ESDI and a few other
 controllers.  I have product description sheets for more.

Hi Chuck:
I would very much like to get copies of both the SR and SM booklets.  If u
are willing, can we work out details off line?  My email address:
t.gardner-AT-computer.org

FWIW, the WD1003V is the 1986 version of this line. I'm not sure exactly
which model shipped in the first PC/AT other than I am pretty sure it was of
the WD1003 family.
