RPN scientific calculator firmware for $13 calculator kit

[toml_12953]

Success! I was able to compile v1.07 and upload it to the calculator. Now that I have all the software in place, future updates will be easier!

One user suggested the universal symbol for roll down (Rv) rather than the loop you have above the 4 now. I'm going to make a similar change to my personal template but with a down arrow instead of the "v". I'd suggest you use that as well but I won't update my public template unless you say OK.
