1. A CPU add-on based upon a 68030 FPGA running at >200mhz. Rather than the Natami Project's approach of adding more and more features to a brand new core, simplify the project by attempting to mock-up a bog standard 68030. Run the 68030 at as high a mhz as supported by the FPGA. As newer and faster FPGAs are released, roll out new CPU expansion cards. This business model would likely be a boon for the classic Amiga community; classic Amigas would suddenly have a regular upgrade cycle again, one roughly tracking FPGA advances.
2. A new "Zorro IV" bus standard. Basically a new, high-clock FPGA buster chip. The chip is intended to reside on a new FPGA expansion card (see item 1). The physical "bus" is implemented via a cable connection to one or more "Zorro IV" cards residing in existing "Zorro II/III" slots. The "Zorro II/III" slots provide the power to the cards, the bus cable handles data transfer to the CPU, and the new "Zorro IV" busmaster chip handles high-clock busmastering. This approach would allow one to 1) add a high speed bus to existing legacy Amigas regardless of physical configuration; 2) re-use existing Zorro II/III slots; and 3) build upon the existing Zorro standard.
3. A new "Zorro IV" card standard. See item 2. The Zorro II/III card layout is reused. Details are provided to vendors on the components needed to draw power from the Zorro II/III slot, the components needed to interface with the Zorro IV cable, and the components needed to adjust the clock of the card on the fly to that of the of the "Zorro IV" cable.
4. A new "Zorro IV" retargetable graphics card. The higher "Zorro IV" bus speed would allow the use of more modern graphics chipsets.
5. A new "Zorro IV" network card. Again, the higher "Zorro IV" bus speed would allow higher network bandwidth connections.
The end of all this is to enable classic Amigas to surf the internet. A high clock CPU, high system bus speed, high resolution graphics, and high network throughput would in combination make classic systems far more usable for practical things (such as reading this site). A cable-based bus would allow old hardware to be reused whatever the physical configuration. An evolutionary reuse of technology such as the 86030, Zorro II/III sockets, retargetable graphics cards, buster, etc., would maintain legacy compatibility while truly expanding upon the Amiga's foundations.
