Look for "nfs", if your particular flavor of unix supports NFS, then the Filer will work with it. On that note, I can't think of a flavor of unix since 1990 that doesn't do NFS.
MAI Basic 4's Unix didn't support TCP/IP, didn't have a compiler, didn't do NFS, but it was Unix. This was YEARS ago, they might have changed since then.
