=== Amiga hardware clones === Long-time Amiga developer MacroSystem entered the Amiga-clone market with their [[DraCo]] non-linear video editing system.<ref name="AutoP5-26" /> It appears in two versions, initially a tower model and later a cube. DraCo expanded upon and combined a number of earlier expansion cards developed for Amiga (VLabMotion, Toccata, WarpEngine, RetinaIII) into a true Amiga-clone powered by the [[Motorola 68060]] processor. The DraCo can run AmigaOS 3.1 up through AmigaOS 3.9. It is the only Amiga-based system to support [[FireWire]] for video [[I/O]]. DraCo also offers an Amiga-compatible [[Amiga Zorro III|Zorro-II]] expansion bus and introduced a faster custom DraCoBus, capable of {{nowrap|30 MB/sec}} transfer rates (faster than Commodore's [[Amiga Zorro III|Zorro-III]]). The technology was later used in the Casablanca system, a set-top-box also designed for non-linear video editing. In 1998, Index Information released the Access, an Amiga-clone similar to the Amiga 1200, but on a motherboard that could fit into a standard {{fraction|5|1|4}}-inch [[drive bay]]. It features either a [[68020]] or [[68030]] CPU, with a [[Amiga Advanced Graphics Architecture|AGA]] chipset, and runs AmigaOS 3.1. In 1998, former Amiga employees (John Smith, Peter Kittel, [[Dave Haynie]] and Andy Finkel to mention few) formed a new company called PIOS. Their hardware platform, PIOS One, was aimed at Amiga, Atari and Macintosh users. The company was renamed to Met@box in 1999 until it folded.<ref name="AutoP5-27" /> The NatAmi (short for ''Native Amiga'') hardware project began in 2005 with the aim of designing and building an Amiga clone motherboard that is enhanced with modern features.<ref name="AutoP5-28" /> The NatAmi motherboard is a standard [[Mini-ITX]]-compatible form factor computer motherboard, powered by a Motorola/Freescale 68060 and its chipset. It is compatible with the original Amiga chipset, which has been inscribed on a programmable FPGA [[Altera]] chip on the board. The NatAmi is the second Amiga clone project after the [[Minimig]] motherboard, and its history is very similar to that of the [[C-One]] mainboard developed by [[Jeri Ellsworth]] and Jens Schönfeld. From a commercial point of view, Natami's circuitry and design are currently [[closed source]].{{Citation needed|date=June 2011}} One goal of the NatAmi project is to design an Amiga-compatible motherboard that includes up-to-date features but that does not rely on emulation (as in [[WinUAE]]), modern PC [[Intel]] components, or a modern [[PowerPC]] mainboard. As such, NatAmi is not intended to become another evolutionary heir to classic Amigas, such as with [[AmigaOne]] or [[Pegasos]] computers. This "purist" philosophy essentially limits the resulting processor speed but puts the focus on bandwidth and low latencies. The developers also recreated the entire Amiga chipset, freeing it from legacy Amiga limitations such as two [[megabyte]]s of audio and video graphics RAM as in the [[Amiga Advanced Graphics Architecture|AGA chipset]], and rebuilt this new chipset by programming a modern [[FPGA]] [[Altera]] Cyclone IV chip. Later, the developers decided to create from scratch a new software-form processor chip, codenamed "N68050" that resides in the physical Altera FPGA programmable chip.<ref name="AutoP5-29" /> In 2006, two new Amiga clones were announced, both using FPGA-based hardware synthesis to replace the Amiga [[Amiga Original Chip Set|OCS]] custom chipset. The first, the [[Minimig]], is a personal project of Dutch engineer Dennis van Weeren. Referred to as "new Amiga hardware",<ref name="minimig" /> the original model was built on a [[Xilinx]] Spartan-3 development board, but soon a dedicated board was developed. The minimig uses the FPGA to reproduce the custom Denise, Agnus, Paula and [[Amiga custom chips#Gary|Gary]] chips as well as both 8520 [[MOS Technology CIA|CIAs]] and implements a simple version of [[Amiga custom chips#Amber|Amber]]. The rest of the chips are an actual 68000 CPU, ram chips, and a PIC microcontroller for [[BIOS]] control.<ref name="minimig" /> The design for Minimig was released as [[Open-source software|open-source]] on July 25, 2007. In February 2008, an Italian company [[Acube Systems]] began selling Minimig boards. A third party upgrade replaces the PIC microcontroller with a more powerful ARM processor, providing more functionality such as write access and support for hard disk images. The Minimig core has been ported to the FPGArcade "Replay" board. The Replay uses an FPGA with about three times more capacity and that does support the AGA chipset and a [[68020]] [[Soft core (synthesis)|soft core]] with [[68030]] capabilities. The Replay board is designed to implement many older computers and classic arcade machines. The second is the Clone-A system announced by [[Individual Computers]]. As of mid-2007 it has been shown in its development form, with FPGA-based boards replacing the Amiga chipset and mounted on an Amiga 500 motherboard.<ref name="individual" />
