Summary     : Unix based emulator of the Atari eight bit computers
Description :
The Atari++ Emulator is a Unix based emulator of the Atari eight bit
computers, namely the Atari 400 and 800, the Atari 400XL, 800XL and 130XE,
and the Atari 5200 game console. The emulator is auto-configurable and
will compile on a variety of systems (Linux, Solaris, Irix).
Atari++ 1.30 and up contain a built-in ROM emulation that tries to mimic
the AtariXL operating system closely.

Update Information:

Atari++ 1.59
 - Fixed the Antic DMA cycle allocation for narrow playfields. Due to misalignment between various DMA allocation slots, more cycles were available to the CPU than possible in the original hardware.
 - Added a cycle-precise Pokey emulation that updates interrupt registers and potentiometer registers on a cycle-by-cycle basis.
Atari++ 1.60
 - Redesigned parts of the pokey emulation. The new version offers the option to be cycle-precise, i.e. pokey interrupts (POTs and timers) arrive now at the cycle. This improves the audio output for the "Electronic Speach Systems of Berkeley" considerably. (Kennedy Approach and others)
 - Redesigned parts of the audio interfaces. The smarter audio output count now clock cycles and generate output for exactly the number of clocks passed. The output frequency still requires dynamic adjustment since the CPU load of the host system is never precisely in sync with the emulated clock.
 - The control mechanism to bring the emulated clock and the system clock in sync has been improved, it is now a PID type of control loop that gets faster in sync than the previous versions.
 - The improved audio output is available currently only for the ALSA and DirectX audio output chains. Oss/OssHQ and SDL remain unaltered. There is, however, little reason to fall back to the less precise chains. Prefer ALSA on Linux and DirectX on Windows.
 - The parser for the keypad stick emulation was still buggy (oh bummer!) and was finally fixed. "Space" and " " can now both be used.
 - The windows emulation of the readdir() primtives still had a bug and could crash the emulator on accessing a network volume. Fixed.
