I’m a vintage calculator tragic! I love what the C43/47 communities are doing in reviving RPL and RPN for a modern audience. What’s even more amazing, is that the DB48x calculator is a singular dev effort by the talented Christophe de Dinechin (I’ve contributed briefly to his code).
If you’re curious to try out RPN/RPL without buying hardware, then both the R47 and DB48x calculators are available as apps on the iOS App Store.
Those of you who want to go deeper down the rabbit hole, I strongly recommend you check out Calculator Culture — he reviews both modern and vintage devices; https://www.youtube.com/@CalculatorCulture

Still looking for the perfect replacement for my HP48GX which died a mysterious death. Actual 48GX are hideously expensive and I’d be concerned they could also just mysteriously kick the bucket.

An open source calc!
Btw calc stands for calculator, I'm just using slang.
