After seeing this, I'll see what can be done about using these (and other common  TI calculators that cost only 5 bucks.) and abusing these into instering mainline code. It's got the potential and hopefully there is an easy exploit. Every hardware has a way to communicate with it.

I *think* there was another topic that expanded on the possibility of hacking this particular calc. further. IIRC it was a no-go.

Yeah true, although I wasn't sure if more work was done on trying to find a solution afterward. I didn't follow these discussions as regularly anymore at one point. Is the calc still sold, by the way?

I think they are still sold. A friend has bought one a few months ago in The Netherlands (might have been Belgium as well). I don't know if it's fully the same calc though. It's white, but looks the same for the rest, and I don't know the full version number, though it starts with TI-30x.
