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.

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!

Tweaks magic formulas.

The computer now at least seeks outward, until this attempt at drive speed calculation fails.

My new belief is that I'm either reading the buffer from the wrong place, or the 68000 isn't filling it for some reason.
