→Orion TI-84 Plus
====Orion TI-84 Plus====
Orion TI-84 Orion Plus is a special model specifically modified TI-84 Plus released by Texas Instruments, in cooperation with Orbit Research, for people with vision impairment. This model has a speech module attached powered by its own ARM processor and reads out keys being pressed, calculation results, error messages, etc., and such voice messages could be redirected to an external Braille display.
None of the emulators could fully emulate this model yet. MAME lists this model as a "bootleg", with its basic functionalities works, but the speech module is left completely undumped and unemulated.
