Ulf's Space Age Calculators
Let's start with the classical HP-35 from 1972
It is the first scientific calculator ever sold...and has no SHIFT key !
Launch the HP-35-Simulator !
Some years later...the classical HP-45.
...and again later, not equipped with LEDs but with the first
alphanumerical LC-Display, the unbelievable HP-41C:
One of the first small case HP-calculators: The HP-21:
This is a HP-25 programmable scientific calculator. The smaller case was designed to reduce the price of the HP-calculators.
The HP-32E was one of the latest HP scientific calculators which uses an LED display. It came to market in 1978 and was designed especially for statistical calculations.
The HP-67 is a real sophisticated scientific LED calculator which is also equipped with an integrated magnetic card reader. It came to market in 1976.
Unique and rare: The HP-01-Calculator-Watch from 1977 !
Contains a watch, a calender, a stopwatch , a calculator and an alarm clock ! The calculator's capabilities are comparable with a HP-38
The stylus to operate the calculator keys is part of the clasp.
