Well that's an interesting question that came up at the beginning of the project but we discarded that approach and this module is written anew from the ground up; so no 16C source code was used at all. That provided a more challenging assignment that has also proven to be much more fun to do.

The CPUs might well be very similar (or even the same?) but the data registers most certainly are not; as far as I can tell the 16C uses 64-bit registers whereas on the 41 that's limited to 56. Or at least that's what it feels like given all the peculiarities in that machine...
