where is Multi?

     I keeps seeing Multi, a molecular modeling program for SGI written at
 NIEHS, referenced both here and on site lists, but I can't seem to find it
 anymore.  THe ftp site on the nameserver at niehs.nih.gov is gone now, and
 ftp.niehs.nih.gov only has some strange PC software that I don't need.  Has
 anyone seen multi lately, and could you tell me where to find it now?
 Thanks In Advance,
