I think messing with the kits isn't likely to produce a working system. 
You need more than the driver to make everything work.

At the very least LES (Layered Environment Services) has to be available.

I've found some notes that suggest that the DST32 and DSH32 both use the 
same driver (ZSDRIVER, as you've found).

The other "busless" one was the DSW21/DSW41/DSW42.

I can't find a WANDD SPD either locally nor online, but (iirc) V1.2 was 
Phase IV and certainly ran on V5.5-2.

A bunch of stuff changed radically in V6.0 so if there was a Phase IV 
release for V6 then it would almost certainly have been post-V1.2.
