RE: HP 45 High Precision Timer
Was first to ask for V1....and probably the last one to implement it :-)

Thanks Werner, it works like a charm !!!

Gluing the PCB was easy, as well as soldering GND & CLK.

The PCB fits nicely.

The little tricky step is to route the red wire under the display & ICs

Then every thing rests easily back in place

Timer precision for my sample is even better than specs given by Werner.

Thank you again for this very elegant mod.
