Description

On January 4, 1972, Hewlett-Packard announced the HP-35, world's first scientific calculator small enough to fit in a pocket - more precisely, Bill Hewlett's shirt-pocket. The HP-35 was an immediate hit with students, engineers, and scientists. Despite its steep price of $395 (about $3000 today), it sold ten times better than anticipated in the first year.
Experience this unique calculator that won HP the prestigious "IEEE Milestone in Electrical Engineering and Computing" in 2009.

Features:
• Photo-realistic look-and-feel
• Three skins: version 1, versions 2 & 3 (1973) and final version 4 (1974)
• Vintage mode and Enhanced mode
• Key-click and key-glow, both optional
• Swipe left across display to correct number input errors
• Cut/copy/paste display value
• Display stack registers and memory registers
• All decimal points but one light when iPhone battery charge drops below 5%

Vintage mode
In this mode, peculiarities of a real HP-35 are simulated:
- original speed of operation
- stack register Z copied to T on trig functions
- leading zeros may be entered; zero can be made negative
- a negative number may be entered by pressing CHS before or after the number
- a keyboard entry or RCL immediately following STO does not raise the stack
- for version 1 only: simulation of a number of known arithmetic bugs
Enhanced mode
- non-volatile stack and registers
- use registers 1 through 9 with HP-45-like register arithmetic
- register 0 works as LastX register

I love my original HP-35. But I can’t take it everywhere so it’s great to have this simulator on my phone or iPod.
