It provides over 60 new functions to the C64-user (e.g. BASIC-Extension, Fastloader and -saver for the 1541 with an acceleration factor of 10, Freezer, Monitor). Additionally there is a graphical user interface (Desktop) with windows (similar to GEM or Windows). From the hardware there is a Reset– and a Freezer-Function. The 1581 is not supported.
