Ratings and Reviews
Wow!
Great! My HP-25 died a few years ago and no-one repairs them any more. It was always at my side for a quick calculation and these days I’m forced to use an ‘equals’ key that still catches me out. Once you learn RPN you tend to think like that and I really miss my ENTER key. I learned a lot about programming and clear thinking by writing a few programs on the HP-25 and it was my first computer.
Thank you for this recreation of my favorite gadget. I haven’t had so much fun since first opening the box that held my HP-25 in the 70s. And the stacks and programs are visible, which is even better. The best couple of bucks I ever spent!
