Free42 – An HP-42S Calculator Simulator

I've had the iOS version of Free42 in my pocket for over a decade now. My real 42S is safe in a drawer. Highly recommended.

Am I the only one who think the 41CX totally outclasses the 42 series?

There is also Plus42 by the same person which is what I use on my phone. https://thomasokken.com/plus42/

I have a 42S and 15C, I tend to use Plus42 the most, then the 15C.

The primary difference is simply the expandability of the 41 series, plus the hacking of synthetic programming.

Outside of that, as a calculator, the 42s is a better, more capable device.

Make no mistake, the 41 series was very cool. How many other calculators had floppy drives, plus whatever else you could wire into the 41.

But the 42s is just flat out a better calculator.

I have Free42 on my iPhone, but I typically reach for iHP48 over the 42. Just more comfortable with it.
