This is a homebrew tap containing a few libraries and a program (TiLP) for connecting to and working with Texas Instruments calculators.
This is TiLP2 version 1.17, this is NOT the current version, but something of a curiosity for me. I can't promise this will work or even build for you either.
I don't maintain the software itself, just the homebrew tap for making installation on Mac OSX easier.
The software itself was created by these lovely people: http://lpg.ticalc.org/prj_tilp/index.html
