(exploit) TI-Nspire - Using the maintenance menu, one can delete the OS and reinstall an older version. (bug) TI-Nspire(1.4.11653) 84+ Emulation(2.46)- CrnchyOS crashes when a program is opened.
(bug) TI-Nspire(1.6.4379) Nspire keypad - I was in a library document, adding a variable. Midway between typing it, The display formed 1 pixel-wide horizontal lines, about 5 pixels apart. I pushed on, and the display did not change. I pushed ctrl-on; the display turned off, and I pushed on, and the calculator turned on, right where I left it.
TI-Nspire Cas (1.6) - dont know if it is meant to do this but at the end of the 99/99 page limit, it was still going for me... a possible exploit i hope! uploaded video here: http://www.sendspace.com/file/ngqkmr by panos yianni (email@example.com)
(feature?) TI-Nspire(1.6.4379) Nspire keypad - One can send earlier OS's to a calculator if you send it from calculator to calculator.
(exploit?) The copyright information on the TI-NSpire states that is uses portions of ssh software. Is it possible that we could ssh into the calc, in the same way the iPhone dev team did?
(bug) TI-Nspire(1.7.2741) While booting Nspire OS once I reached the thatched loading screen it allowed me to switch key pad to 84 keypad but still loaded Nspire OS.
(bug) TI-Nspire(1.7.2741) while at file list screen with home menu displayed, the key combination enter + menu + home + escape forces cold boot.
