The latest HP12c shares the same internal hardware with the HP15c Collector's Edition. There should be no reason for not being able to create a firmware that accepts the VoyagerSave procedure!

This firmware would allow to create as well Solution Pacs. We could have, for example:

• Trigonometrics
• Black and Scholes formula
• Several games (NIM, landing, etc.)
• Breakeven analysis: solve for sales price , quantity, cost.
• Statistics - normal distribution

Any other you may be interested on?
