NOTE:

The EXCALIBUR MENTOR is the exact same computer as the NOVAG MENTOR 16 which came out in 1989.Betweenthe years 1995 - 2000, Excalibur must have made some agreements with Novag to enable them to rename and repackage some of their previously released computers.Some of these were:

Excalibur Karpov 2294 = Novag Emerald Classic Plus
Excalibur Mentor = Novag Mentor 16
Excalibur Viper = Novag Amethyst
Excalibur Escort = Novag Opal

Some minor modification in level choices and other features might have been made but none of these features provide a noticeable difference in game strength.
