Thanks for those links.
Not to be pedantic, but his project uses is an S3BOARD, which is
different from an S3EBOARD.
I happen to own an S3EBoard, so I happened to see the difference.
There is a significant difference between the boards, not the least of
which is the type of memory onboard, SRAM(easy to access but not much
storage), and DDR (much better capacity but requires dedicated controller)
Both boards are very popular and I've really enjoyed my S3E.

Look at Brad's implementation

Pfui, it's in Verilog :-(
But the old simple S3E board he uses is still one of my favorite boards!
It's one of the coolest FPGA boards you can have.
There is also the

Oh, that sounds more
"reasonable".
