RPN HP calculators: HP29C (my first one) and HP41C (did university with it).
A long time ago, some demon soul from hell decided to kill them product lines. The world never was the same, afterwards.
- madengr 10y agoThey still make a 35S which is what I use. I have four 32sii still sealed in the clamshell.
- eitally 10y agoThey're dead? I just gave away my HP48 whilst cleaning house. :(
- realo 10y agoHP48GX on eBay : 365$. Now you may weep...
- msbarnett 10y agoHuh. I have a G and a GX sitting in my closet...
- chx 10y agoI have a 128kbyte HP 48G in my closet and I will never part with it. It's a fine bit of hardware hackery from ages long, long gone by: four RAM ICs stacked on top of each other and a friend of mine did the wizardry soldering where most of the legs are just kinda ran together like so many tiny waterfalls and the control legs are soldered separately.
- ctkrohn 10y agoHP still makes RPN financial calculators. I recently switched to using an HP 12C at work, after holding out for a long time. It's amazing how quick it is once you get used to RPN, and I love the solid feel of the hardware. You can pick one up for around $50.
- a3n 10y agoI have an HP15C and an HP12C on my android, from HP. Maybe they offer your calculators.
- realo 10y agoI already have an excellent HP41C emulator on my iPhone... this is not what I am talking about. It is the physical experience of holding an HP41 (or older HP2x) calculator in hands, and the feel of the keys. Nothing comes close today. Also, you could hack the HP41 with what was called "synthetic programming" ... Great fun. http://www.hpmuseum.org/prog/synth41.htm http://www.hpmuseum.org/prog/synth41.htm
- copperx 10y agoI still don't understand how "algebraic" input won ... it requires so many more keystrokes. Perhaps it makes sense for students in lower grade levels, but once you get proficient, RPN is a no-brainer.
- dtamhk 10y agoHP 11C, light saber of our time.
- scentoni 10y agoI completely agree. I lost my HP 48 during a move and still mourn it. I bought an HP 41C on eBay to comfort me, because I yearned for the 41 I saw advertised in Scientific American as I was growing up. I loved writing programs in https://en.wikipedia.org/wiki/RPL_(programming_language) https://en.wikipedia.org/wiki/RPL_(programming_language), a Lispy dialect of Forth.
- auxym 10y agoSwissmicros makes replicas of the 15 and 41 (among others). I need to get one to replace my 35s (keys starting to break after a couple years) some day.
