RE: newRPL: [UPDATED Jan-18-16] Firmware for testing available for download
I have installed the new firmware on the HP-49g+. To start with it didn't work, but leaving all batteries out for ten minutes fixed the problem. I couldn't clear the RAM with the ON-A-C key sequence mentioned in post #39 - on my calculation, this brings up a screen saying "EXCEPTION - RPL break requested" and "clear memory" isn't one of the options shown. Is there a way to clear the RAM on a HP-49g+ without taking all the batteries out and waiting?

One possible bug: y^x gives an incorrect answer if asked for a fractional power of a negative number (e.g., try -529 0.5 y^x). I don't know whether y^x is intended to give complex results from real inputs, but it should probably throw an error (like sqrt does) if not.
