manual:chapter1:installation

This is an old revision of the document!


What is needed:

  • HP 50g (although this calculator was discontinued by HP in 2015, used calculators can, of course, always be found on Ebay). It is recommended to have fresh batteries installed.
  • SD card (2 GB, formatted with FAT16)
  • ROM file: newrplfw.bin (get the latest from here)
  • Text file: update.scp

newRPL ROM installation Instructions:

  1. The update.scp text file contains only the name of the ROM file, newrplfw.bin. Note that the text file must be a *simple* text file, so it cannot have embedded codes that frequently accompanies documents created with, for example, Microsoft Word. The text file can be created on a Mac using TextEdit, Windows using Notepad, or on linux using Vi (or any text editor of choice). Put both the update.scp and newrplfw.bin files in the root filesystem of the SD card. Insert the SD card into the calculator.
  2. Enter the Boot/Self Test Mode: Power the calculator OFF, press and hold the plus(+) and minus(-) keys simultaneously, insert a paper clip into the “Reset” hole on the back of the calculator, remove the paper clip and then release the plus/minus keys after a few seconds. The screen will have two options when in this mode: 1. UPDATE CODE, and 2. SELFTEST (the Boot version and the serial number appear at the bottom of the screen).
  3. Enter mode 1. UPDATE CODE
  4. Choose 2. CARD

The ROM update will take about 2 minutes during which time a series of Hex values will scroll down the screen. At the end of the update the total size of the ROM will be printed, press ENTER. If all goes well you will be presented with the newRPL display interface. Since the ROM filename itself doesn't contain its version, use the function `VERSION` to return the installed version information.
