K2 Facilitating Thermistor Calibration

David Woolley (E.L)
I'm getting close to the point at which I populate the thermistor board
and I came across an article saying that the quarter watt resistor was
deliberately not an eighth watt in order to make it easier to change it
to calibrate the board.  Has anyone devised good ways of making it easy
to adjust, e.g. by using a variable, or using a header, so the through
hole joints don't have to be remade? Is there enough clearance to do
something like this.

(As an aside, it would have been nice to have done the correction in
firmware, so that you linearise the calibration curve, but I guess that
would have needed another microcontroller hanging off the AuxBus.)
