Woodstock Display Upgrade (a sight for sore eyes)

[markhen]

@Matt - yes, already done - as described in posts #2 - #4 there are 2 capacitive switches accessed by touching the top of the calculator - one turns on the SI mode, the other turns it off (back to normal exponent display). At the moment the default is to normal display mode (when calculator is turned on - there is no memory of mode during power off).
