Back to RPL ! (HP50G)

[David Hayden]

It should go without saying, but switch to RPN mode. I believe that algebraic mode is the factory default.

Get an SD card (2GB or less) for backups and to store every program ever written . I use a 128M card because the calculator starts faster with it.

As someone else suggested, get HPUserEdit to create programs on a PC. Note that the menus are in Spanish by default but there is a way to change them to english.

Debug4x is great for SysRPL programming.

For real fun, consider HPGCC. This lets your write C code and run it natively on the 50g. It's about 100 times bigger but also 100 times faster, and you can always store the "real" program on the SD card and create a small stub on the calc that loads the program and evaluates it.

The 184 page "users manual" is more like a quick reference guide. Don't try to use it to learn the calculator. Use the much larger "users guide" or the AUR.
