How do you map the much larger 67 keyboard onto the 25?

Good question!

My solution:

If you press the first row HP-25 buttons normally it behaves like pressing the second row buttons of the HP-67. If you press for longer than 1/2 s it invokes Function keys A-E. It is very convenient and easy to use.

Now, as I learned much more about the HP-67 firmware, I think there might be a solution for a direct HP-67 ACT replacement with the existing "new ACT" hardware. The challenge will be the real time requirements of the card reader. Please don't expect me do achieve that very soon, but there is now a chance for it.

Long-press - I agree an easy and intuitive solution. Thanks for clarifying.
