First RPL+ calc available now
oliverue
calc available, and you can play with it now: the 1.3.5 update
containing RPL+ just posted. Free ND0 will post in a few days.
In case you haven't heard before: ND1 is the first non-HP calc that
can run many 50g programs. It fully supports the User RPL language
with a partial, but 400 instructions-strong, command set.
This is not a better calc than the 50g. It's far less complete. But
it's developing fast, and it has its strengths. If you're a calculator
enthusiast, they may be to your liking. For starters, it's
programmable in JavaScript and uses HTML5 for the stack and all
graphics. Graphics use the Canvas object. Arbitrary JS code can be
tied in, even external files. There's really no limit to the things
you can display, or to the extensions you can make.
There's a proper architecture behind this calc, and it's wide open for
3rd party development. To my knowledge, this is the first calculator
that allows you to build your own data types. It allows extensions
that are indistinguishable from built-in functionality.
If you'd like to breathe fresh life into RPL code you wrote, maybe
you're interested in making your work available as a "shared folder"
for ND1 and upcoming MorphEngine calcs (Android, Kindle in the works).
Not everything will run, but what does, will run at least 10x faster
than on the 50g.
See http://naivedesign.com/ND1/ND1_Reference__HP_Comparison.html for
benchmarks, incl. for RPL+.
Thousands of ND0 and ND1 users *will* download your work. (Folder
downloading in these calcs is a one-tap affair.)
ND1 is a paid app, but it's free to anyone who contributes. A
contribution doesn't have to be complex. One cool RPL function, for
example, is all it takes. (Also looking for a Spanish translation.)
ND0 is free and will remain free. It's limited to displaying 3 stack
positions but otherwise fully functional.
Cheers.

editing on the computer.
There's always been a way to exchange an entire folder via WiFi. It
requires a custom server set-up, though, and the use of a JSON editor.
There's a new method that abducts the VISIT key and makes it into a
"get code from computer and edit" key:

This enables you to write code on your computer and run on ND1 one
second later. It works via WiFi.
You can use your favorite editor to write your code, incl. HPUserEdit
(I suppose).
Any RPL transcode characters (\>>, \->, etc.) will be automatically
translated into Unicodes.

What systems do ND0 and ND1 run on?
I have a Droid 2.

CalcPad is the next MorphEngine calculator: same engine, different UI.
It will ship for iPad but then also for Android, taking full advantage
of the bigger screen of tablets.
