RUCS no longer supports Sun 3's except as X terminals. We don't think there are any Sun 3's in use at Rutgers as anything other than X terminals. So far tests with X terminal configurations show that there is no problem either operating during the transition to 2000 or booting after 2000. It appears that the proper date it stored in non-volatile memory. It is nearly certain that serious year 2000 issues would occur in Sun 3's being used as normal workstations or servers.
Some testing is still in progress.
We have not tested Sun 3's for year 2037 compliance.
