The Whipple Museum of the History of Science at Cambridge University here in the UK has a permanent collection of personal calculators which was kindly donated by Francis Hookham (who sadly died in March this year). The bulk of the collection is HP and the museum published a book last year detailing the whole of their collection (great read throughout) but it also includes a sizeable chapter on Hookam's HP calculator collection and the cultural changes that came about during those nascent days of personal computing when HP engineers were most definitely the thought leaders.
I know the story has been told a thousand times over in multiple internet hangouts but I think the history is particularly well researched and written (as you'd expect from an academic writer).
Apologies if you've seen it before (I did check to see if it was mentioned on the Museum forum, but couldn't find anything).
Here's the Museum blurb specific that adds extra detail and context.
