During the life of the HP 48 series calculator, a number of firmware modules or Pacs were offered, they dealt with various subjects. There was one on Celestial Navigation, called the Nav Pac. Re this, a couple of questions.
1. HP no longer offers them, are there any available, if so where and or from whom.
2. What price glory?
3. Will the HP 48 series Nav Pac install and operate on the current HP 50G?
Please advise and thanks.
