App Description
48sx is an emulator of the HP48sx, a vintage RPN calculator.
The HP48 SX is a vintage RPN calculator that many of us remember with fondness. I used this calculator 30 years ago and fell in love with it. Now, I can carry it in my pocket every day!
The HP48 SX emulator for Android is available on the Play Store and GitHub. The bundled ROM is free for non-commercial use. No nags, no ads, and completely FREE!

48sx is a modified version of droid48, specifically tailored for the HP48 SX. Credit goes to Arnaud Brochard (author of droid48 for Android) and Eddie C. Dost (author of x48 for UNIX), who created an emulator of the Saturn processor in 1990.
