Description

This article is from the Apple II Programming FAQ, by Jeff Hurlburt with numerous contributions by others.

009- What Operating System environments does the GS support?

    The GS can support several. Some of the more popular OS environments
include ...

DOS 3.3- usually Beagle's Prontodos or some other speeded version of
the original DOS 3.3. This is the 5.25" diskette-based disk operating
system used for years on earlier Apple II's. It's commands are
designed for use from BASIC programs or from the keyboard. Many old
Apple II games and other wares are on 5.25" diskettes which boot DOS
3.3.

ProDOS 8- e.g. ProDOS v2.0.3. This is a disk operating system which
supports a variety of devices (e.g. 3.5" drives, hard drives, etc.)
and allows sub-directories. Commands are very similar to DOS 3.3 and
are designed for use in BASIC programs or from the keyboard. BASIC and
'system' programs can also utilize direct CALLs to well-defined ProDOS
Machine Language Interface routines.

Apple Pascal- This is an early 1980's implementation of UCSD Pascal
which can run on 40-column and 80-column Apple II's.

System- Originally called "ProDOS 16" and later "GS/OS", the
collection of 'system stuff' (which includes GS/OS) is today called
"System". The System Finder utilizes Toolbox routines to supply a
super-res desktop, Windows-like environment. Both ProDOS 8 programs
and 'GS Applications' (i.e. wares that need GS/OS to run) can be
started from the desktop. Depending upon factors such as installed RAM
and presence of a hard disk, System will usually be System 5.0.4 or
System 6.0.1. System 5.0.4 is generally appropriate for 1.25MB or
smaller non-hard disk GS's. Booting a reduced System 6.0.1 often works
fine for running Sys 6 software, too. System 6.0.1 is definitely
recommended as the default System for larger memory GS's with a hard
disk. --Rubywand and David Empson

GNO- GNO is a UNIX-like multitasking environment for the Apple IIgs
which runs on top of the native operating system, GS/OS.
