Should keep them cool though! Who cares what they look like. Might
even get to appreciate their Batman/Gothic look !

I had asked Mariss before, if a guy could have a 'low drive' ie 1/10 step
and then shift to 'overdrive' ie 1/1 or 1/2 step by putting logic to his 210
headers (instead of jumper blocks), but didn't hear back. The software
guys seem amenable to such a thing (taking just one output pin for 'overdrive').

It seems such an obvious answer to a continual nagging problem
(of resolution vs rapids).
