GNO/ME will work on any Apple IIgs with at least 2 MegaBytes of memory and a hard drive.
You should have at least 5 MegaBytes of hard disk space free for GNO v2.0.4.
GNO version 2.0.6 is much larger than previous versions. Even if you are only installing v2.0.4 at this time, it is recommended that you reserve at least one 32-megabyte ProDOS partition for GNO-specific files.
We recommend 4 MegaBytes of Memory and an accellerator card, especially if you will be using GNO with many background processes. A modem and access to an on-line service will greatly speed access to technical assistance and new utilities as they are made available.
