MS-DOS software under sysV R4 : Question

[Pierre Racz]

I am planing on (finally) moving from DOS to UNIX but I own a lot of DOS
software that I would rather not leave behind (mostly CAD stuff).  The 386 
architecture should make it possible to be able to run DOS applications 
under UNIX.  But how well is this supported ?  How well does it work
for graphic software ?  What kind of surprises am I in for ?

Based on Wade Guthrie's "Chosing a 386 UNIX", and having placed inquiries
with 386 UNIX vendors, I am leaning towards the DELL sysV R4 since
it does not seem too overpriced for the features it offers 
(Unlike XENIX).  

And finally are there any sysV386 sites in Montreal willing to let me
see their system and ask them a few questions ?

Thanks.
