Did the HP-65 record data?

Alternatively, you can store and load registers along with the program on the same card by simply flipping a switch. This actually eliminates the need for data cards or data-loading programs. Touch-ID-enabled devices even let you protect your register data.

BTW, the "67/97 program with a more accurate approximation where the constants are intended to be stored on a data card" Dieter mentioned above may now be downloaded for RPN-67/97 here. (Scroll down to the Math section.)

Yes, Willy. Thanks for making the vintage modes an option. That way, a true 65, 67, 97 experience can be had and, when you want to take it up a notch or two, you can.
