The WD1000 documentation is on Al's site (bitsavers.org).  I sent him index 
files with the parts listed, even giving the page number:

wd1984storageProducts_03

wd1983catalog_01


Others docs are available on the net.  I recently saw 2 controllers for sale 
but I rarely see them.  I've been thinking of a project to emulate one, they 
are simple and the precursor to the IDE.  With very little effort it should 
be possible to interface it to an IDE drive.
