My first calculator was an HP-25e (physical science degree) followed by an HP-65 (civil engineer degree) followed by an HP-41cx (USAF commission) with a 25c - 29c & 65 - 67 upgrade somewhere(s) in between. Graduated to an HP-19Bii (DoB) for my MBA, with a smattering of non-HP's on my OCONUS deployments (Texas Instruments {SR-52}, Casios, Sharps {1211-1500} & Radio Shacks {PC-1⁄2}), etc.

BEST!
