Re: HP calculator prototype? Message #2 Posted by Don Shepherd on 26 Feb 2012, 9:14 p.m., in response to message #1 by David Griffith
I don't know about the HP-8s, but many low-end calculators have the four directional keys to enable the user to recall recent entries, edit them, and execute them again.
I can't imagine that a typical user would benefit from that capability very much.
