OMTI has discontinued the card due to lack of demand. But it seems
to me that there is a misunderstanding about this 1:1 interleave
business. SCO, like any other OS, doesn't know about the interleave
factor of a track buffering controller. Track buffering controllers
exist with the standard AT compatible interface. Therefore, you
don't have a problem unless the WD1007 doesn't have a track buffer.
Since much less expensive controllers, such as the WD1006 and
Adaptec controllers have track buffers, I would expect that the 
WD1007 does also. 
     The "ST506" paramter you mention has absolutely nothing do do
with the controller to bus interface, or the interleave factor.
