My original FPGA-64 project didn't go unnoticed. The story started when Jens asked me if I would like to port my FPGA64 project to the C-One board. Initially I wasn't really motivated as it worked correctly on a Xilinx Spartan-3 kit and I didn't have any C-One board myself. We discussed the options and Jens offered to send me a C-One board so I could do the port myself. The original plan was to focus on using the 65816 as it is shipped with all the boards.
