Is this for real or is just Interactive's marketing?  They distribute
Norton, right?  Does the software use any ISC specific feature (file
system, drivers) ?

Now for the follow-up question.  Why?   How come a text-based
application  like Wordperfect can't be made to run under all of the 386
plataforms.  How bad are things going to get when they come out with
an X-Window version?  You would also have software written to a
specific X-Server?

There are 6-7 vendors of 386/486 Unix out there.  Unless off-the-shelf
software can run unchanged across plataforms, it seems that, except for
SCO and ISC, they would all have to close their doors. (And we would all
be lining up to buy Microsoft's OS/?)
