I was wondering why you take on so many things at once.Maybe it would be better to work on just one system at a time, test it and put it out -then work on the next one?
This is easy to explain.
There are several people involved in the project
Igor Majstorovic, did develop the Vampire600 accelerator card for the A600, and the Vampire500 card for the A500. These cards to exist already.
Jens Künzer owns a Terasic stand alone FPGA system.
This system offer great performance for price. The system was sold for $90
The FPGA is fast enough for 600 MHz 68020 speed.
The sys tem has audio and video out.
And comes with dual fast memory controller and 256 MB fastmem.
So he wants to bring uo this one.
Christoph Hoehne has designed the Apollo-Phoenix Cyclone 5 CPU accelerators for A500/A1000/A2000. This is a great system not only able to provide a very good speed up, but also includes GFX card update and more features.
He of course does the bringup of this card.
Thomas Hirsch - is probably well known as the inventor of the NATAMI currently tests the integration of Phoenix CORE in the NATAMI as option for people instead using an 68060.
