Tell me about the HP 67

[hth]

I have a 67 I obtained in a trade that I never have powered up. I should probably do so, but the problem is that I never got enough motivation to try it.

If I could get some rechargeable batteries that could be taken out and loaded in a smart charger outside, I would be more inclined to try it out. Is that possible?

The buttons with letters are auto assign local labels in a program, the HP-41 has that too. Typically you use them for different entry points in a program and as a reminder you can write what they do on a magnet card and slide it into the slot (similar to what you can do on the HP-41 card reader).

I am a little bit put off by that it loses memory when turned off, but the build quality feels very solid. The keys rattle on mine if I shake it sideways, I suspect that is normal?
