Hi Bob,

GemTools relies on things in $GEMSTONE/bin/extent0.seaside.dbf. If you want to connect to a simple $GEMSTONE/bin/extent0.dbf then you can use Topaz or GBS (with the proper license/keyfile). Also, if you are willing to use Windows you can use Jade [1] as it does not rely on special code being in the database already. You should be able to connect to any GemStone database with it.

There were some unimplemented messages being sent in the original code base, which gives me the impression it is a work in progress. So, we will have to see wether the GLASS and Pharo versions diverge or merge.
