Can any TI calc Equation Edit??!!

[debrouxl]

Sorry for bumping the topic, I hadn't read this area of the board for a while
I'd just like to add to Han's post pointing eqw, that there's another great third-party equation writer for the TI-68k series: Samuel Stearley's Hail Equation Writer, http://www.stearley.org/exw.html

And I agree with the previous posters about the whole calculator market offering laughably underpowered hardware by modern standards, at insane price tags. Newer components wouldn't necessarily consume more energy: for instance, a Cortex-A5-based microcontroller instead of an ARM9-based microcontroller, or probably a Cortex-M using newer chip technology than a 68000 or Z80 ASIC from over a decade ago.
