MSDOS
Atari 8bit System Emulation
XL-It! 0.20 by Markus Gietzen, IMHO the best Atari 8-bit Emulator for the MSDOS Platform, a must get.
XFormer 2.5 is another Atari 8-bit Emulator for the MSDOS Platform, you will need this file to get the needed ROMs for XL-It!
Atari ST Emulation
PaCifiST - An Atari ST emulator for PC, very good and functional.
New features in v0.41:
• Direct MSA
• Real ST keyboard
• STF samples support for FAST machines)
• Optional 68000 prefetch emulation
• Some bugfixes,more directives
• new bugs...:-)
UNIX
Atari ST Emulation
STonX an Atari ST Emulator for Unix/X based systems, there is a SVGALIB version for Linux, another must get.
TOS Images
For any of the ST emulators to work your going to need TOS Images, For Games and such get TOS 1.0 and for GEM Applications try TOS 2.06.

Atari 1040STe 
The 1040STE is the ultimately
upgradeable Atari Computer.
Add in SIMMs, throw in an accelerator, go to TOS 2.06. It all
works and works well, because the STE is the only machine in
the ST series that was designed with upgradeability in mind.
The 1040STE was introduced in 1990 and has stereo sound,
TOS 1.60 (later 1.62), and a 720K floppy drive. We can
upgrade the floppy drives in these machines to 1.44MB.
Essentially, the STE is the same as the
1040STF that preceded it except for its sound capabilities,
expanded 4096 color palette, and its
SIMM memory upgradeability.
Atari TT030
The TT030 is an ideal graphics
workstation and can use up to 266MB of RAM. It runs a cached
32MHz 68030 processor with a 68882 math coprocessor. The TT030
works with VGA-style
color monitors and 1280 x 960 Moniterm-style monitors. TT's that
shipped with TOS versions less
than 3.06 included 720K floppy drives. TOS 3.06 machines include
1.44MB floppy drives. An
upgrade is available. TT030's address RAM in two separate
sections: ST RAM and TT RAM. ST
RAM is used for video and other DMA functions, while TT RAM may
be used for high speed
68030 burst-mode operations. Most programs can use both types.
Includes cartridge port, MIDI
ports, stereo out jacks, one parallel port, four serial ports, a
LAN connector, one VME card slot,
and can support one standard 3.5" half-height SCSI hard disk
internally with no host adapter
required. SCSI out port for hard drive expansion. Detachable
keyboard that is Mega ST/Mega
STE compatible.
Atari MegaSTE
The Mega STE has a 16MHz,
cached 68000 processor, with a slot for an optional 68881 math
coprocessor. It shipped in two versions first with TOS 2.05 and a
720K floppy drive, and later withTOS 2.06 and a 1.44MB floppy
drive. Older machines may be upgraded. It has one VME cardslot
for expansion (great for video cards) and can support one
standard half-height 3.5" SCSI harddisk drive when used with
the optional internal host adapter. Includes cartridge port, MIDI
ports,stereo out jacks, three serial ports, one parallel port,
and one LocalTalk LAN port. Up to 4MBRAM using SIMMs. Works with
any ST monitor. First ST to include NewDesk desktop. Detachable
keyboard is Mega ST compatible
Atari STacy
The Atari STacy is a complete,
portable ST system. It is a favorite machine for musicians. It
includes a built-in trackball, a floppy drive, a hard disk, and a
monochrome LCD supertwist display.It uses a special version of
TOS 1.04 and can usually support expansions such as the ICD
AdSpeed ST accelerator and the AT-Speed PC Emulator. Includes
MIDI ports, serial and parallel
ports, and mouse/joystick ports.
