newRPL: [UPDATED April 27-2017] Firmware for testing available for download
By an overwhelming number of requests (ok, just one but looks better that way) I've made available for download an early firmware image for the adventurous.
It can be downloaded here:
UPDATE: ** USE LINK BELOW FOR LATEST DEMO IMAGE ** - SEE POST #39, #70, #118, #159, #184, #245, #267, #274, #313, #329, #349 #391 #436 and #500 BELOW FOR LATEST CHANGES

newRPL firmware demo

Update: The documentation project is well underway! If you downloaded the ROM above, don't forget to check out the new wiki at:

The newRPL Documentation Project wiki

Update: The latest image is still alpha quality, but it's not as green as it may seem from the old post. It includes many features and can work as a reliable scientific calculator. Much work remains to be done, but this image has improved much since it was originally posted. For more updated information please refer to the project website:

OLD AND OUTDATED INFO HERE.... (original post)

Everyone is invited to test-drive it and provide feedback. Being an early demo there's many things that don't work, some because they aren't implemented yet, and some because they are buggy. I'd appreciate comments on the latter case so we can start debugging this into a more polished product.

What to expect and not to expect:
* There's no menus, but most commands can be typed in alpha mode.
* The VARs menu is fully functional. It can be hidden/shown by long-pressing VAR.
* No status area yet
* Command line is not multiline yet, and there's no begin/end/cut/copy/paste. Skip word, go to the end, etc. are mostly not implemented yet.
* Keyboard is mostly functional, but there's keys not bound yet to their commands (like HOME or UPDIR, you have to type them).
* The new alpha mode will seem very strange at first, but will quickly grow on you.
* The STO/RCL function was moved to the HIST/CMD location in the keyboard due to the new VARs menu keys interfering with it. Everything else stayed where the 50g had it.
* The OFF function was moved to the battery compartment for now (pull a battery!). The OFF key performs a Warm-Start due to technical difficulties.

Feel free to explore the docs here, and the detailed status to see which commands are already implemented here.
There are a few more commands (several that deal with matrices) that were implemented but not shown in the list yet.

To install the rom, simply put it on an SD card together with a file called 'update.scp' that contains the text 'newrplfw.bin' inside (no quotes). Then do a normal ROM update and it will pick it up. Upon reset, you'll get a confirmation screen that warns you that the initial install will wipe out all RAM. This is your last warning before you lose anything that wasn't backed up.
To restore to stock firmware, just do a paperclip reset and re-flash the stock rom, but you'll have to use the 2MB special version that's in the .zip file to get Port 2 working again.

Let's concentrate the feedback and questions on this thread.
Enjoy! (and report back!)
