I know the person that developed that, one thing to note is that it is 
designed to be used in the Atom, where the 6847 fetches the data 
directly from the video RAM, not using the SAM to do DMA like the CoCo / 
Dragons etc.

Though this implementation has the video RAM within the FPGA, it has not 
been tested in combination with a SAM and so would need some work to get 
it going.

Cheers.

Phill.
