NEW: HP 15C Collectors Edition

[Johnh]

Just chipping in about emulators, particularly for the Hp15c, on Android.

I think there are only two on Google Play that come up as being installable on recent-model Android phones, with the current Android version. These are JRPN15 by Jovial, and Touch RPN by Stendec. There may be others that can run If already installed (eg, if transferred from older phones with Smart Switch), but are prevented from new installs by the Google-police since they have not been certified for the current Android. I think that includes the official Hp sim for the Hp15.

But the two I note above are both really good and seem fully functional for use as an on-phone alternative to a physical Hp15c.

Touch RPN includes ad-supported versions of all the Voyagers It's great to be able to explore what they all do. Then you can spend a few $ to get ad-free on the ones that you want. I actually have an earlier version, that I bought before all the Voyager models were combined, just for the '15. It has transferred through several of my phones, but is not available now The things I like about the Touch apps are being able to save and load full memories, as many different versions as you wish. This makes it a great scratch-pad for developing new programs, ahead of keying them into a physical calc. Also, I think the Touch apps have the best look and feedback feel of any of the past or present sims for these calcs. You can also maximise the button and display area, trimming off the bezel, so that the working area is almost as large as the real calc, on a standard-size Galaxy phone. I used to have the official Hp15 app, but uninstalled it because I preferred the Touch version.

I think JRPN15 is newer, also fully functional. It not quite as nice and natural looking as Touch, and doesn't have that expansion feature to trim the bezel so the working area stays a bit smaller. But, two nice features:

You can edit certain colours, and I boosted the orange gold tones of the f key and labels to make them brighter, matching the real Hp15C-CE tones, rather than the deeper reddish tones of earlier ones.

The other feature of JRPN15 that I like is very compelling. Apart from saving and loading memory states, it can also copy the program memory to the Clipboard. Then you can paste into a text app and get an instant program listing with line numbers, key codes and key names. That's very useful for when transferring to the real calculator. Attached is a screen shot of a trivial program, just to illustrate (Label A does a 1/x and then returns).
