Step-by-step to upgrading your HP50g rom.

Revised on August 2009.

If you are unsure of your ROM version on your calculator, use command VERSION (press twice ALPHA key, type VERSION and then press ENTER key) to find this out. The HP 50g will return two strings, with the first saying something like Version HP50-C Revision #2.08 (in the case your HP50g was set to Algebraic notation mode, you have to press down arrow key to see this information).

This procedure is potentially risky, you may put your calculator into a zombie state! If that happens, you should try the update using another computer.
