I don't know your technical skills but if you look at the docs you will see 
the WD1000 was the start of a series of devices that defined a uniform way 
of communicating with disk drives that later was called IDE.

I'll look at the pinout but I believe that the WD1000 uses a subset of the 
IDE connector pinout (and software commands).

The biggest differences would have to be:  256 byte sector limitation, 
Geometry is fixed in BIOS.
