One way of describing this groups' work would be "Thee who had problems".  One of things they were supposed to do is making SUN Ultra 5 computer VO (Visnjan Observatory) got from CARnet work.  They didn't do that, but it was not their fault (really), computer was broken so it had to be returned to Zagreb for repair.(SUN was returned repaired to VO nearly one month later where it is now doing it's job) Other things they were doing was working on new software for VO and improving existing one.
