Wow - thanks guys but unfortunately a bit beyond my knowledge and understanding"
What I really need now is to find a Ladybird "
Guide to Oscillators and Crystals", a Look and Learn "
Oscillator/Dividers/Counters" supplement but appreciate I've no chance of sourcing an Eagle Annual cutaway drawing explaining "
How a CMOS 4060 IC works"!
These days it's all "Idiots Guides .. " !
Looks like more R&D is needed on my part so I'll get onto this Project in the New Year.
Meantime best wishes to everyone for the Festive Period and for a prosperous New Year.
