Wow the early stuff...Had the aneroid barometer...not too good as you mentioned, remember always tapping it? Had a mercury min/max thermo..it had these little markers inside the glass that would stay at the highest and lowest readings..push a button to reset. It had a 6 ft cable which you put out the window. I've had a lot of equipment...Much of it I still have sitting in the basement...looks like a weather museum. First digital unit was a heathkit thermometer...remember those?
