Amiga computer remade
Several Amiga clones/remakes are in the works. Each with a slightly different aim, some for total compatibility, some to be faster and offer more features. Hopefully someday whe'll be able to also document which differences these make to coders. (probably especially to interest for 680x0 / hardware hitting coders)
Recent Amiga computer clones/remakes
Minimig is an FPGA-based re-implementation of the original Amiga 500 hardware (PAL version). It's based on available hardware documentation and info from WinUAE(?). The project was made public on 5 december 2005 and has gone opensource in july 2007.
- NatAmiga (Native Amiga)
This reimplementation is based on implementing the features documented and described in the HRM and then expanding on it 'within the Amiga philisophy'. It is claimed to being able to display 1280x1024 in 32bit, handle bitplanes and chunky, 24bit audio and a 100 times faster blitter.
project started oct 2005, made public in december 2006
This project aim to totally reproduce the output of the Denise, Gary, Paula chips, CIA and later even the Agnus chip. This means you could run an Amiga on partly the original chips and part on the FPGA.
the oldest project with the aim on AGA compatibility. However this project was abandoned and never released. Plans included an AA chipset (next gen AGA chipset) with 20x bandwidth of AGA, 32 bit blitter (up to 20x faster), Unified Memory Architecture, 16-bit sound, HD floppy drive support)
Amiga clone which used AmigaOS, but only supported RTG (Cybergraphx). It was meant for the video market.
- Phase5's amiga-clone projects
(see http://www.amigau.com/aig/phase5.html for detailed info on these)
was a clone developer by Phase5. It did however not emulate the custom chips, so whether it's a 'clone' is debatable. It was announced in 1996 and in the beginning of 1998 they announced it was postphoned. Unfortunately in 1999 they admitted it had been cancelled and in january 2000 Phase5 filed for liquidation proceedings.
Was to be the official successor to AGA. Compatible with OCS/ECS but not with AGA. Had features like 4-6x times faster blitter and multi-write copper instruction. Commodore in it's infinite wisdom decided to scrap the AAA project.
