RE: A question about alternative power supply for hp41 series
Good question! I take a look at the circuit again and the parte is 15mq040, which, actually, is a scotky diode, not a zener.
A zener in that position, I believe would have no x-function as voltage limiter....
So, it would be neccessary a voltage regulator too...
Its getting complicated....
