RE: Best HP Financial Calculator
I remember that the 28C I bought when it was just released back in 1986, although having the battery side cover, did not show the broken port problem. The cells pushed the door very lightly. I used it for years and, finally, sold it ten years later with the door in perfect condition.
Lately I bought a NOS 28S. The door broke the very first time I closed it with the cells in place, they were exerting a BIG pressure on the door. Somebody "enhanced" a working design. |
