Hello all!
A friend has just completed a prototype replacement module for the HP 01. It uses the LED block and keyboard from the original. So they must be undamaged and functional.
He is targeting mid summer and a cost around 800 euros. He does all the work and the watch is purported to be more accurate, less energy consuming then the original.
Most of the damage on the twenty or so that I have repaired were to the gold traces on the porcelain. I have never seen a damaged keyboard but that is a small sample size. I suggest a thorough examination of the led wire bonds with a digital or analog microscope to ensure their continuity.
I will let you know more as the info comes in. Here is a taste of what he does, his passion is for all things HEWLETT PACKARD LED. I did a talk in Nashville on his Woodstock board upgrades and have completed the HP 25 enhanced GPS to one of my old non-functioning LED HP 25 calculators and upgraded five others for myself and others:
