HP 41(CX) - ADDING MEMORY
Hi, people

Recently I'm using a lot my 41CX for programming, as my faculty doesn't accept graphical calculators.

I have seen great projects for 41 series, even the 41CY, but all of them are expensive to me.

The 41 searches for labels into ROM ports. Well, if so, I was wondering if I couldn't connect some Arduino to a port and load it with programs. It would simulate some ROM pluged to a port. So, I could use it's large memory to hold my programs, not ROM (or even them).

The program should be input to Arduino by a microcomputer but preferable in ASCii legible caracters, not in byte instructions (as we read on hp41 display).

Any help? Any material to read and understand better how to try this?
