We hooked up ATN and RESET inputs to the microcontroller so "all" it
needs is a full implementation of the firmware and a host-side program
to write the data to USB.

I have no plans to implement this but if someone else did, everything is
GPL and in the OpenCBM repo.

For me, the s2iec is good enough.

Since the 1541-Ultimate has ethernet, ram, and fpga, it seems like it
could do this with some software work.
