hp rpn scientific calculator for android apps

There is also an emulator for HP48GX for the iPhone, called i48.

It is a HP48GX emulator, but it also has a HP-48SX mode with a simplified look. However, the other day I found a modified version of it called Droid48sx that looks just like the real thing. On my Android phone, until recently I used the Droid48 emulator. The good news is that since 2000, Hewlett-Packard are generous enough to allow the use of ROM files even if you don’t own a calculator. It requires a copy of the ROM from a HP48SX or GX (depending on which calculator you want to emulate). In Windows I use the wonderful Emu48 by Christoph Giesselink . There are several emulators for HP calculators available, both for computers and for smartphones. That could be a good thing, as nobody ever asked to borrow my calculator when they forgot their own… There were disks with programs ( Joe Horn’s Goodies Disks) and all kind of information, including how you could open your calculator and solder on more memory… I also had several friends who used HP calculators, but the big majority of the students in my school did not understand the Reverse Polish Notation (RPN) used by HP on all their calculators except the financial models. There was always a fairly large community dedicated to HP calculators. It was the replacement to HP-28S, and was later upgraded to become HP-48GX. I also got the battery-operated infrared printer, HP82240A.įinally, in 1990, I bought my last HP calculator, the HP-48SX. I used it for a couple of years, and then switched to HP-28C and then (the next year) I upgraded to the HP-28S, with more memory. So I got the then brand new HP-15C, a scientific programmable calculator that still is one of the best calculators ever made. In 8th grade we were allowed to start using calculators in math. It was the non-programmable version of the HP-25, with red LED display and rechargable battery pack.

He also got my family our first calculator, an HP-21. He connected it to a server back at HP and downloaded pictures to print on the plotter. Through him, I got to see some early computers, once he brought home a computer, a plotter and a very early aucoustic modem. For the first few months he lived with me and my family, until he was able to find an apartment. Back in 1974-75, my cousin moved from Blekinge in southern Sweden to Stockholm after getting a job at Hewlett-Packard. My personal history with HP goes back to my early childhood.
