Also strips some cruft of prior guesses.

260843e5b1 Starts poking at a pure total-based formula. 
On the assumption that any relevant DC offset will fall out in the wash. This causes one 400kb disk to boot in a Macintosh 128kb, another couple to do reasonably well. So it's better than what was here before.

e3f22e5787 This should actually be PWM, I think. 
I'm just unsure of exactly the proper formula, owing to my ignorance on basic electrical engineering. Research ahoy!

5149f290d0 Starts trying to formalise just-in-time execution. 
Which, at least, simplifies Cycle/HalfCycle to Cycle run_for usage via template.

827c4e172a Cuts a third from the Program struct. 
Observation: [source/destination]_address are always one of the address registers. So you can fit both within a single byte.

Net effect: around a 12% reduction in execution costs, given that this reduces the size of the instructions table from 3mb to 2mb.
