- jsjohnst 5y agoI had an HP48GX in the early 90s and loved it. Still probably my favorite[1] calculator I’ve owned and I wrote so much code on it back then. [1] although my TI-92 was a close second after it came out a few years later as it could do symbolic integration unlike the HP48
- opencl 5y agoRPL is great, they kept making the 50G (which was basically emulating the custom CPU from the 48G on an ARM microcontroller) up until 2015. You could even make your own simple GUIs, I wrote a few that I used a lot in school. A resistor color calculator and some statistics-related ones.
- daniellarusso 5y agoMy favorite calculators. I had a 48G that was destroyed and a 48GX that was stolen from an autorepair shop, while the car was in for service.
