(
The
Operating
System)
Atari TOS is the operating system released in 1995 by Atari for its 16/32 bits computer series.
At first, Atari had licenced both
CP/M 68k (lower layer operating system) and
GEM (upper layer graphical extension) from Digital Research Inc. As
CP/M 68k prooved to be too slow when accessing floppy disks, Atari decided to write its own lower layer from scratch,
GEMDOS based on the next and faster operating system standard, i.e.
MS-DOS. This is why
GEMDOS is compatible with
MS-DOS FAT? filesystem.
This mixture of
GEM by Digital Research and
GEMDOS by Atari was named
TOS, for Tramiel Operating System, and later became
The Operating System.
Below
GEMDOS, Atari also wrote
BIOS and
XBIOS responsible for dealing with Atari hardware. Within the higher layer of
TOS, Digital Research had already divided
GEM in a lower layer called
VDI and a higher one, built on the latter and called
AES. See the
TosDesign section for an in-depth discussion of
TOS architecture.
