(I don't have a phone number).

According to a paper I have  of  theirs,  they  have  linked  GIS
(MIPS,  MAPII,  GRASS)  with a general dynamic simulation package
(STELLA) on the Macintosh.  (actually many Macintoshes).

Check the Journal: Ecological Modeling in 1991  for  a  paper  of
theirs   called   "Spatial  Ecosystem  Modelling  Using  Parallel
Processors.
