HP 35 – 40 years old today

hp35.pngThe HP-35 was HP’s first pocket calculator and the first scientific calculator. Its award winning approach brought a range of innovations (first product to have both ICs and LEDs), put many a slide rule on the shelf.


There is some interesting history about the calculator on-line (including the problems based on the lack of precision in the mainframe computers that effected the testing of the calculator).


You can still buy a version today.

Opps, I jumped the gun by one day. I guess that's what happens when you queue up posts.

Good afternoon,

I am electronics student of the National Pedagogical University in Bogotá, Colombia. I'm doing my thesis about the first pocket calculator (HP-35) and would like any information about it. I tried to contact the team at Hewlett Packard in Colombia but I could not find anyone who provides this information.

I would appreciate if you can give me a contact of who handles these issues.

Thank you very much.

Not sure who the contact would be, there is quite a bit of information out there. What kind of information are you looking for.
