The major differences besides the appearances are: Monochrome TI-Nspire comes with two different kinds of keyboards, depending on batch: Clickpad and Touchpad. The OS could be downloaded officially from here, but boot1, boot2, and manuf have to be dumped from an actual calculator with PolyDumper. Using third-party emulators requires boot1, boot2, manuf, OS, and optionally diag dumps of the calculator. TI-Nspire™ (CX) (CAS) Student Software and TI-Nspire™ (CX) (CAS) iOS app are the official commercial emulators released by Texas Instruments. TI-Nspire is the flagship series of Texas Instruments graphics calculators, equipped with QVGA monochrome/color LCDs, ARM-based processors, a mini laptop-style trackpad for controlling the mouse cursor, and a computer algebra system (depending on model) inherited and enhanced from TI-89's AMS. ↑ 1.0 1.1 1.2 Also supports emulation for other Motorola 68000 based calculators including TI-92(II/+) and Voyage 200.TI-89 could be considered as a miniaturized version of TI-92/Voyage200, as they share literally the exact same hardware and software architecture (that is also why some TI-89 emulators could also emulate TI-92/Voyage200), while TI-92/Voyage200 is huge in size thanks to their horizontal screen and QWERTY keyboard. TI-89 is a series of graphic calculators equipped with Motorola MC68000 microprocessors and computer algebra system called Advanced Math Software (AMS). Requires French residential IP address to access. ↑ Only available on non-CAS monochrome TI-Nspire models with TI-84 keypad attached.↑ 1.0 1.1 1.2 Also supports emulation for other Zilog Z80 based calculators including TI-73/81/82/85/86.MAME lists this model as a "bootleg", with its basic functionalities works, but the speech module is left completely undumped and unemulated. None of the emulators could fully emulate this model yet. 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. Orion TI-84 Plus is a specifically modified TI-84 Plus released by Texas Instruments, in cooperation with Orbit Research, for people with vision impairment. Including TI-83 Premium CE (Python Edition) and TI-84 CE (Python Edition). eZ80: Featuring Zilog eZ80 microprocessor with color LCD and rechargeable lithium-ion batteries.There is only one model in this generation: TI-84 Plus C Silver Edition. Color Z80: Featuring Zilog Z80 microprocessor but with color LCD and rechargeable lithium-ion batteries.Including TI-83/84 Plus (Sliver Edition) and all their variations such as TI-83, TI-84 Plus Pocket etc. Monochrome Z80: Featuring Zilog Z80 microprocessor, monochrome LCD, and AAA batteries.Notice that assembly programs written for one generation won't be able to run on a TI-83/84 with another generation of hardware. There are actually 3 generations of TI-83/84 hardware, despite all of them being categorized under the same TI-83/84 model number. It's unclear whether they will actually look into it - "The OS of my calculator is damaged and requires recovery" could be a fairly reasonable one. It could be officially downloaded from here, but a reason is required. Using third-party emulators requires a copy of the operating system of the calculator. TI-SmartView is the official commercial emulator released by Texas Instruments, with a trial period of typically 15 days.
