Bitcoin mining on a calculator? :)

[Dave Britten]

Let's see, from a quick watching of that video of him doing it by hand, I see you'd need a majority function, a sort of bit multiplexing function, parity, bit shifts/rotates, and sums. Definitely not stuff the 41C was built for, particularly since it's all being done on 64-bit unsigned ints.

The 42S and 48* might be able to pull it off with far less hand-made bit manipulation code. Maybe the 16C, too. Does it have enough program space, and 64-bit word size?
