Re: HP-15C stuck in USER mode Message #3 Posted by Tom Ligon on 2 June 2011, 3:50 p.m., in response to message #2 by Mike Morrow
My basis for comparison is Brand X (no RPN), my HP-35, my HP-67, and my HP-48GX. I still have the first two, but rarely dig them out as their batteries are history. I gave the -48GX away (I bought it when I thought I'd lost the -15C, and by the time I got it I used a computer for the fancy stuff).
The 15C, OTOH, runs for years on three button cells, programs like my -67, and always makes me smile.
I never had a -42S, but I can understand why you would like it ... many similar charms.
