It's alive! (HP 25 w/Panamatik ACT)

[pito]

Hi, I own an HP-25 in a great condition, I added the zener protection diode and I inserted a set of new NiMH accus around the year 2000, and I've been charging the unit once per 1-3years (otherwise it sits on the bench), still the same accus inside, and, interestingly, it always works when I switch it on before the charging.
Great work with the ACT chip, congratulation!
Btw., I've been thinking to put the chip into my unit as well..
