truth is, i don't use an rpn calculator for my normal calculation needs i use a ti-89 because it has a full symbolic math package it would be easier to use if it were rpn but afaik hp never made a calculator with this much software crammed in. i could easily be wrong. i havent bought a calculator in many, many years, because the ti-89 hasnt broke

The TI calculators were clearly the best ones because they let me play Tetris and DopeWars instead of learning anything in math class

I played a far more faithful reimplementation of Tetris on my HP 48SX once I spent my allowance on the link cable and started using the ftpmail gateway to get games over UUCP I also hooked a cute girl up with it over infrared when I was at a math competition

do you seriously not have an HP 48? shameful this is something you can and should rectify pretty quickly (one thing that’s cute is that the HP 95LX uses the same style of keys, also happens to run Gold Hill Common Lisp 1.x pretty well given that it’s an 8088 machine)

BORAT VOICE MY FATHER had one of those Business Analyst calculators from HP when he started an MBA (never finished it because BORAT VOICE MY MOTHER went back to finish her PhD), it was real nice. I had Ti-83, 86, then 89.

i only ever had an 83 because i borrowed it on a semester basis from the school. not one of those overachiever kids who had their own personal calculator. it wasn't even a plus model -- still had the square case and angled screen later i found an 83+ at value village for 10 dollars because it wasn't working but i opened it up and it was just corroded batteries. still use it to this day. ok thanks for reading, like and subscribe

I was sure the 86 had differential and integral poo poo built-in but it looks like that was 89-only. Which, looking back, actually makes sense because I remember we started doing babbys first differentials at the end of Pre-Calc junior year (first half of 1998) and I quickly figured out how to make my brand-spanking-new 89 do all the work for me and went back to loving around with BASIC. I still can’t do literally any math.

eschaton posted:no i had to look this up i knew the ti-99 was based on a pretty reasonable chip similar to a 6809, so i had previously assumed it wasn't any worse than its contemporaries, but as usual, eschaton is right wikipedia posted:Only the program counter, status register, and workspace pointer registers are on the chip; all work registers are kept in RAM at an address indicated by the workspace pointer. [..] it was not that weird, back then, to keep the register file in ram, because ram was fast compared to the cpus of the day it's extremely weird and bad to have the register file at the wrong end of a multiplexer and 4-cycle pause for every request

yeah having a workspace pointer and register file in RAM is just fine and very much a minicomputer thing (the TMS9900 was a single chip no-MMU implementation of the TI 990 minicomputer architecture) but making you go through the video controller for “real” RAM was absolutely horrible for performance and then of course everything was supposed to be written against a virtual architecture implemented atop the native one, which is why TI BASIC was so absurdly slow some successor machines (and contemporaries) based on the same CPU were much much faster

I have an HP-15C from 1982 and an HP-15C LE from 2012. The C LE is worth 4x what the the C is. How does this make sense? e. Is there any source for (original model) screens other that broken donors? The screen on my 15C is cracked, but it doesn't obstruct any characters.
