HP should offer a free hardware upgrade

[oldhpfan]

Just for the history, the HP-25 had a minor bug (as I recall for a couple of very small values it wouldn't calculate sine correctly). We were offered a 'send in the calc for repair' offer. I didn't bother because the bug was so esoteric but later when my 25 stopped charging I got it back with a note that the chip responsible for the bug had been replaced too.

Does the rev c prime have anything else besides the wireless fix? Not sure I'll bother if that's it I knew it didn't work when I bought it...if you didn't need some dongle to make it work than yeah it might be nice...and I don't need calc to calc. As for resale value well by the time I'm through with it it will be worthless anyway unless it's an antique...my 67 is in a box somewhere hope it will be worth a fortune soon .
