48SX options

[Phrede]

I find myself taking an exam with math for the first time this century and in need of a handheld. No phones, no computers allowed type thing. "No Problem, I'll just pull out my trusty 48SX" I thought. S/N 3038Axxxxx After fresh batteries and blowing off some dust I've found the display is dim. Contrast works but doesn't help. I'm heartbroken, we've been thru a lot together and it's like losing an old friend.

I'm a huge fan of RPN and will need any replacement to be RPN. I use mostly emulators on my computers and phones with not much handheld use. I would prefer not to spend a lot for this one event. But then I don't want to have to remember "It's algebraic" when I should be focused on the exam.

I'm about two weeks out so any kind of repair path seems unlikely.

What are my options? Does HP have a lock on RPN? Used market for scientific types? Is this a common issue with a magical quick fix? Is HP repair available even if not in time for my exam, I can't part with the old girl and can't leave her like this.

TIA
