This is my first post. I was an HP employee from 1979 to 2013, joining HP right out of school. I have been an HP41 fan since I was issued an HP41C in December of 1980 - I still have that calculator and it works just fine.
I have been gathering up my calculator related items and I peeked at the prices on Ebay for some of the modules I have. I was absolutely floored at the prices! I assume the prices reflect the demand. I was curious, which module is the most sought after?

Like other toys mainly collected by retired fellows like classic Collins radios, prostate rumbling Harleys, and “warm” vintage McIntosh tube amps, the prices are dictated by the market.
