Nice. Who knows how many 10C "emulators" exist? I do not mean Free42-like simulations but 'firmware-interpreters' based on the original firmware of the real thing.

It looks like even before Voyager support was removed from Nonpareil, it only emulated the 11C, 12C, 15C, and 16C -- not the 10C. I wonder why? Is the hardware different in some way?
