I took an exam today where only TI calculators were available. I felt I was caught between some older models where the TI interface was not quite worked out.

The HP-35: Consumer Electronics, an Origin Story (codex99.com)
Sometime in late 1971, Peter Nelson, from Hewlett-Packard’s Corporate Relations Department in Palo Alto, enlisted Karen Cambria, from the Automatic Measurement Division (conveniently, in the same building), to pose with their new electronic device, a scientific calculator they named the HP-35. Norton Pearl took several photos of Karen with the calculator and it was this photo that ended up in the press kit.

The Strange Case of the Rogue HP-12c Calculator (dm319.github.io)
The HP-12c is probably the most iconic financial calculator. Not being in finance myself, and in fact being terribly bad at that kind of thing, I never quite got the purpose of these special-purpose devices. My ignorance came to a halt due to an unfortunate combination of my fixed-rate mortgage period ending and Liz Truss happening, and I was driven to a sudden keen interest in the ‘time value of money’ (TVM) calculation.
