Hi, apologies for using up some of your neurones with this but it is Christmas
I stumbled across your forum while trying to get to grips with a Geocaching puzzle. The clue is obviously based on a 4011 and 4025 CMOS circuit but the showers of rust as I root about in the box room at the back of my brain are obscuring my view!
The output (the ** below) will be the back end (minutes and decimal seconds) of some latitude/longitude co-ordinates - the figures at the top of the diagram are slightly clipped - they are 53.**.*** and 002.**.*** It is very likely to be 53.00.*** or 53.01.*** and 002.06.*** or 002.05.***
Do you think I'm going to have to get into pinout diagrams and datasheets from Fairchild or is it not that deep?
TIA
Mike
