HP-41 CX emulation app...excellent program 1

[Ingenuity]

The HP-41 was a very popular programmable calculator amongst engineers, especially structural engineers back in the 80's and 90's.

I purchased my first RPN calculator in 1982 ( first year at university). It was a HP 41 CV and it cost me AU$410. Used it for 20 years+ continuous years until something went wrong in mid 2000's. Purchased a HP 48 GX next but was not the same.

So now I have a iPad and just purchased an app that is probably the best HP emulation program I have used.

It has different skins that you can overlay and it looks and feels just like my old 41. It also has a "printer" that looks like the old 41 printer. Cost was US$25, but includes all the math, stress, structures and many other app pacs that were available back in the 80's.

Also works on my iPhone too.

I picked up a free HP 48gx emulator too from the Apple App Store, but no where close to the 41 in functionality.

I am not associated with the software in any way, just a happy user.

Anyway, though it may interest some 80's engineers that enjoyed the 41...good times.

I have i41CX+ on my iPhone (the + version includes a CAS system, but I haven't really used that feature). It is a very nice ap and it handles all the modules I like to use. There are lots of HP emulators/simulators available for various platforms. I have HP41-CX and HP-42S emulators on my Palm TX, which I still use from time to time because it's better than my iPhone for certain things. In addition to the i41CX+ on my iPhone, I also have two HP-42S emulators (Free42 and 42s), i48 (an HP-48GX emulator), and two HP-12 emulators (Fin-12C and 12Cal). The iTunes store has more. I also have more than a dozen emulators for my home PCs, but so far have only loaded Free42 and V41 on my work laptop. The HP-42S has been my favorite calculator for 24 years, but the HP-41CX does some things the HP-42S doesn't, which is why I use both. I also keep a working HP-48G+ in my desk at work for several things it does best, but overall I have never warmed to the 48 or to RPL programming.
