NatAmi 68060/N070 board series
Standard-formfactor board with one or more PCI-slots
Chip and Fastram as seperate DDR2 SDRAM banks. Onboard soldered chips.
68060 CPU a expansion Card with SRAM; May be replaced by a 3rd party CPU card (eg. PPC)
Future-upgrade-path for onboard N070-CPU (by Firmware-Flash)
NATAMI Specification:
The NatAmi is a stand alone device not an extention to another system.
- GFX: SuperAGA chipset on board
Compatible to AGA and enhancing it.
- Supported Resolutions:
320x256 - 1280x1024
- Supported Pixelformats:
Planar 1-8 Planes, HAM 6/8, 8bit Chunky, 16bit Hicolor, 32bit Truecolor
- Video and VGA:
- 31kHz VGA:
Digital and Analog VGA/DVI-I output
15kHz screens are automatically scandoubled to be displayed both on TV and VGA monitor.
15KHz screens are not atuomaticly flickerfixed as scandoubling looks better for old games and demos.
- SVideo:
PAL/NTSC video output through SVideo connector.
15kHz are shown directly without conversion (SVideo quality).
All screens are scaled to 720x512 (or 720x400 on NTSC) as long as the VSYNC is 50/60Hz
corresponding RGB-analog signals may be available on internal (on board) connector.
- Genlock:
an SVideo input connector is available also. The background color can be exchanged with this signal.
This feature is not fully implemented as of today.
- AUDIO: Paula style sound
4 Voices
From: 8bit Samples x 6 Volume
To: 16bit Samples x 8 Volume
- COPPER: including original AGA copper
- BLITTER:
Fully compatible with AGA-AMIGA
Speed of SuperBlitter is many times faster than AMIGA AGA blitter
comparisons will follow.
- 2D Enhancements:
In Chunky/Hicolor/ or Truecolor pixel mode the Super Blitter can "cookie cut" copy BOBs.
Like the AMIGA Sprites, a "cookie cut" copy needs no blitting mask.
This enabled the blitter to use less memory and to work at double speed compared to planar blits.
- 3D Accelerator:
Texturemapping Blitter enhancement.
Provides Mipmapping, Subpixel 4 way interpolation, Light sources, Antialiasing, Alpha blending.
- Amiga backwards Compatible IDE controller supporting PIO and DMA
- Amiga Compatible Floppy Disk controller
- 2 PCI slots onboard to allow later upgrading (3rd available with riser-caard)
- CPU on CPU-card
68060 CPU on board for instant compatibility with AMIGA software and Operating Systems for Amiga-Hardware
- CPU expansion slot
Allows upgrade to another CPU (e.g. Coldfire/PowerPC)
Full documentation will follow to allow 3rd party upgrade designs.
- New enhanced and performance optimized 68K-CPU planned as free upgrade.
Work is in progress on a new fully compatible 68K CPU, AKA N070, providing high performance for todays multi-media applications.
This CPU will be implemented as softcore into the main logic design. Once the CPU is finished it can be upgraded by reflashing the firmware.
