Actually put me in the camp of a SuperCPU 128 owner who would LOVE to see $100 clones. The more of them out in the wild, the more developers would support it.
I wonder if it is possible to get the FPGA64 core (that should be running on FPGAArcade soon, if not already) enhanced with SuperCPU (or SuperCPU-like) functionality. Certainly a faster CPU core must be possible on the FPGA. In addition, a C65 core might be a fun thing to play with.
