In short, yes.

Are you telling me that a Ti83+ will be usable on my nSpire soon?

The older Clickpad and Touchpad Nspire models had an interchangeable keypad and a 84+ emulation mode, though it was incomplete, inaccurate and slow.

And yes, a ZX Spectrum emulator is clearly possible on the Nspire, as TEZXAS for the TI-68k series ( http://tezxas.ticalc.org/ ) is more than a decade old, and the Nspire has higher raw power (but less programmability) than the open TI-68k series.

My father BEGAN his computer career on a Timex Sinclair Z80. I can emulate one of these, can't I? I suppose that hardware emulation other than just the CPU is required, things like displays, memory mapping, storage, interfaces, and data transfer are all crucial components of any device, emulated or not. I'll have to emulate a Z80 when I get my CX CAS

I know that the old click/touchpad nSpires had the interchangeable 84+ keypad. My friend owned two of them because his parents were rich and bought one for his sister and one for him. His sister never used it, and he never used his either,he usually borrowed on of mine. So he just had them in his bag all the time and I messed around on them, testing compatability between certain ASM programs and Applications written for the real 84+. He wouldn't mind giving me the one that he damaged the screen on I bet, and I know people love getting help from people testing things on a clickpad! The thing was slow, and one of the worst problems it had was emulating the display. Certain graphing could actually completely f*ck the display up, IIRC. Playing games was a very dangerous thing. Though, he had a very old calculator OS on his nSpire and his 84+ was 2.44 I think.

Looks like you're making good progress . The CX and touchpad download links 404 for me though, clickpad link works.

Awesome and much-needed project! Maybe someday I can program TI-83 Plus programs on a TI-Nspire so I don't have to carry three calculators in my backpack all the time.

And then there's the inevitable: Emu8x on TI-84 Plus on TI-Nspire

EDIT: ...in nspire_emu in VirtualBox

Insert obligatory comment hoping Axe will work on it when finished.

Definitely keeping an eye on this
