ULTRIX FILE SERVICE FOR DOS, MAC

[Jim Rosenberg]

Does anyone out there have experience with or know of products that allow
the use of an Ultrix server (DECSystem 5400) as a file server for PC DOS
and Macintosh.  I understand that DEC is releasing their PCSA (correct 
acronym ?) software for Ultrix, but I am interested in other packages.  We 
want to provide transparent access to database files and a manager, as well
as other applications, for DOS and Mac users;  ideally, users would never 
see a difference from DOS / Mac access of local files and applications.

Thanks in advance for all the help.
