The HP-50G is such a pain in the backside to get into upgrade mode.
I can't go to the upgrade mode to save my life. Did it once about a year ago. It just keeps resetting. and pressing the +_ and the reset hole with a paper clip, it takes two people. In this day and age with microprocessors HP surely could have made it easier to do. Let the software place the calculator into download mode. Sheesh. My Ti-89 is easier to upgrade.
Guess I'll just keep the old rom.
