I Found this HP27 with the broen keyboard lastweek among some other stuff.

Wondering what to do with it.

Repair it or sell it. The HP-27 was HP's first "do everything" pocket calculator. This calculator did math, statistics and business functions (but was not programmable).

One interesting bit of trivia for this model is that it was recalled after units had already been built, packaged and stocked in a warehouse, but before it was released to the public.

Professor William Kahan recalls his role in this small part of HP history and gives yet another example of why HP (and particularly Dave Packard) were so highly regarded back then.
