NatAmi prototype motherboard.

NatAmi (short for Native Amiga), is an Amiga clone motherboard developed by Thomas Hirsch and the NatAmi Team. It is aimed to be fully compatible with the original AmigaOS. The first developer version of the Natami motherboard is expected by 2010. The HDL sources for programming of the FPGA chips is closed source.^[1] The hardware language chosen is the proprietary Altera hardware description language.^[1]

On 18 Sep 2009, The Team revealed an evaluation version of NatAmi baseboard. While the prototype was based on C-One mainboard, the new NatAmi 16 LX is a brand new board, which will be a foundation of the incoming developer board. Furthermore, NatAmi 16 LX board is to verify hardware and peripheral design concepts.

Specification

NatAmi 16 LX board

Evaluation version of NatAmi baseboard.

Memory
- 128MB ChipRAM (max)
- 128MB FastRAM (max)
Graphics
- 31 kHz video out, 15 kHz video out, 15 kHz video in
Audio
- audio in, audio out
Peripheral
- SyncZorro, PCI, 2.5" IDE, 3.5" IDE
- simple (1.1) USB
- serial port, parallel port, ps/2 keyboard, ps/2 mouse, floppy disk, joystick ports

The final developer version is going to have 32bit RAM and 512 MB RAM in total instead of 256 MB as for LX version.

Final developer board

The future NatAmi will not be an expansion card but a complete motherboard aimed to be compatible with the original AmigaOS by Commodore.^[2]

CPU
- Motorola 68060 CPU for instant compatibility with AmigaOS software
- The 68050, a new 68k compatible CPU for high compatibility, good performance, and low cost.
- CPU expansion slot (allows upgrade to another CPU)
Memory
- 256 MB ChipRAM DDR2 SDRAM
- 256 MB FastRAM DDR2 SDRAM
Graphics
- Tami, an integrated 3D graphics and texture mapping processor.
- SuperAGA chipset (compatible with AGA)
- Supported resolutions: 320x256 - 1280x1024
- Supported pixelformats:
  - Planar 1-8 Planes
  - HAM 6/8
  - 8-bit Chunky
  - 16-bit Hicolor
  - 32-bit Truecolor
  - Also planned and confirmed: 24-bit Hybrid Chunky-Planar colors with three 8-bit Byte-Planes chunks for each Red, Green and Blue color component.
Audio
- more than 4 hardware audio channels (Paula style)
- 24bit audio with 16bit sample support
- Hardware support for mixing an unlimited number of channels
Copper compatible with original AGA copper
SuperBlitter compatible with original AGA blitter
High Density (1.76 MB) Amiga compatible floppy disk controller using normal (1.44 MB) PC drive
Amiga backward compatible IDE controller supporting PIO and DMA
2× PCI slots (for later upgrades)
