GS/OS 4.0 DOESN'T support the AppleShare File Server; however, GS/OS 4.0
CAN use an AppleTalk printer.
The AppleShare IIGS Workstation Software provides ProDOS 16 from System
Disk 3.2, which allows Apple IIGS access to the AppleShare File Server.
Later versions of GS/OS ARE compatible with AppleShare. Apple highly
recommends upgrading to GS/OS 5.0.4 or later.
