Atari Coldfire Project

The Atari Coldfire Project (ACP) is a volunteer project that has created a modern Atari ST computer clone called the FireBee.
Reason for the project.
The Atari 16 and 32 computer systems (ST, TT and Falcon) were popular home computers in the 1980s and the first half of the 1990s. Atari withdrew largely from the computer market in 1993, and completely in 1995-1996 when Atari merged with JTS and all support for the platform by Atari was dropped. The systems Atari had built became increasingly left behind as newer and faster systems came out. The few dedicated users who were left wanted more processing power to develop more-advanced TOS applications, paving the way for a number of "clone" machines, such as the 68040-based Milan and the 68060-based Hades, both of which were considerably more powerful than the 68030-based TT and Falcon and the 68000-based ST/STe. These machines support ISA and PCI buses, which make the use of network and graphics cards designed for the PC possible (something no original Atari machines could do). The machines also support tower cases, making it possible to use internal CD drives.
A new clone named Phoenix never made it to market in final form. However, the powerful rev. 6 68060 CPU it would use did make it into a new accelerator board for the Falcon, the CT60/CT63 series, which meant that, for the first time, the Atari platform had a CPU rated at over 100 MHz. The use of a high-speed bus and PC133 RAM also accounted for a big performance improvement and significantly increased the Falcon's on-board memory limit from 14 MiB to 512 MiB with a CT60.
These systems were not mass-produced and are now hard to find. While the CT60/CT63 needs a Falcon “donor” system, and is still not as powerful as the ACP potential system could be, the ACP will use a completely new design, moving away from 68K CPUs to the newer ColdFire class, more powerful than even the fastest 68K chips while still having a largely similar (but not completely compatible) instruction set. It will also allow for the integration of many I/O ports that are currently only available through extensive hardware modification on the Atari platform.
Specifications.
The specifications for the ACP have changed considerably over time, in response to advancing technology and price considerations. However, it seems the following will be in the final design according to former Atari Coldfire Project homepage:
Operating systems.
On the 8MB ROM, FireBee devices have the following pre-installed software:
There's a ready to use FreeMiNT and GUI environment setup with applications ported to work on ColdFire which can be ordered on CompactFlash card with the device.
µClinux has also been ported to FireBee.
Compatibility.
There are different strategies for dealing with the differences in ColdFire and 68K instruction set and opcodes:
FireBee FPGA doesn't yet provide DSP functionality which means that any Atari Falcon specific programs requiring DSP won't run. Many Falcon games and demos use it to play background music.
