Dear HP41 enthusiasts,
I am looking for the circuit diagram for the HP41CX halfnut version.
Searching an electrolythic condensor which is wired in parallel to the +UBatt terminals. I want to supply the upper housing shell of the halfnut on the workbench - without using the original battery holder
I use this setup for replacing the internal silicium battery cell from a HP41CY (HP41CX halfnut with internal RAM-Box)....
