The wp34s is back!
Finally we received the overlays of the current approved design and we are ready to update the firmware of brand new HP30b s into the most powerful RPN calculator ever - with permision from the mighty HP42s
Eric's newer overlays are better than the previous, initial batch. You can choose between coloured shift keys or white; and you can choose as well between both division signs: / and the two dots with a dash in the middle. All are in the overlay for you, the user to choose.
There has been significant evolution since we updated the first calculators - now you can do matrix operations with them as well.
