How do I get into maintenance mode with the TI-84 keypad?

I got this untested for $18 with an offer, so I do not have a lot invested into this just based on what I paid. However, it only comes with the TI-84 keypad, which is making me think the seller probably used it for school and had to use the TI-84 emulation since they usually come with a Nspire keypad OR at least the Nspire+TI-84 keypads. However, I am not getting either Nspire keypad with this - just the TI-84 one.

With a lot of these it seems to be an OS issue (which is why I bought it). Reloading the OS is not an issue since I have the correct cable (MicroUSB), but I do not know IF you can access the maintenance mode for the Nspire OS with this keypad - I do not see any instructions on how to do so, and Reddit says no.

Is it possible to access maintenance mode with the keypad I got should I need to reload the OS, or do I need to purchase an Nspire specific one if there’s an OS problem and it’s recoverable?

As far as the other keypad, this is the one my Nspire shipped with - likely alongside the TI-84 one:

I was hoping you'd gravitate towards this since you're the TI expert.


@nick I'm working on it. I should have an answer by the end of the day!


@thelastmill Alright. Hopefully I can get in without the Nspire keypad if it's bad software, which seems to happen a lot with the "untested as-is" TI graphing calculators. At least they're cheap if it's not possible and has bad software if I need to get in.

Hopefully the seller ships the Nspire keypad if there's no other way to get in, but that's usually not the case with eBay.

It looks like it is possible! You’ll want to press Graph+Enter+8. Here’s the instruction for each possible keypad:

One important thing about the cable, the Nspire requires a Mini-USB connector which is slightly bigger than the more common Micro-USB you mentioned. :)

Note: I had help from Adriweb on this one since I’m more experienced with the TI 84 lineup rather than Nspire calculators.

Yeah that's what I meant :P. The Nspire was enough of a deal I didn't need but I could also afford it as a backup in case I need it. At $18, it was hard to say no, especially if I can repair it - even with the screen damage. It seems like a lot of them are an easy fix too if you know what to run away from - notably busted screens on the B&W series and any Nspire Cx for the time being.

I'm just used to Micro and -C now so it was a second nature error. I knew it was mini.

Eventually I'll need to get an Nspire keypad to use it beyond a emulated TI-84, but knowing it can be done gives me a lead on repairing it before I buy one.


The calculator is going to be here today. Hopefully I get the Nspire keypad but it isn't in the photo but I don't think so - yeah, it didn't. It turns out TI ships it with that keypad I didn't get, but the 84 one was free by mail. And the mark isn't as bad as it looked in the photo - it's minor.

Just needed a cleanup of the battery terminals to get it working :-). These usually go for $35+ with both keypads. Can confirm the key combo works. I was able to get cables and the keypad for $8.99 vs $5 for just the keypad for this too, so it's mostly complete short the student software I see copies of. Still not too bad compared to what they go for working.

I'm not worried about the firmware being at 4.2.0(?) not being in school - this was too cheap to pass on, especially since I know someone who may need my TI-84 for testing since it's better accepted then the Nspire, especially since it's already a 2.55MP factory that's hard to downgrade.


Awesome, I'm glad it worked out so well for you @nick ! One question, if you have the TI 84 keypad in, does pressing [mode] > [alpha] > [S] bring up stats for the calculator's OS and BOOT code? If so, what are they?


@thelastmill The TI-84 diagnostic does not work on the Nspire. Goes back into entry mode. As to why I was confident I could get it going, this was the issue. They didn't clean it, so I knew I had a good shot at getting it going. I see some without the slide cover for less, but no proof repairs weren't attempted - which is a sign it was tried and probably a lost cause.

I don't get anything there but I do see 2nd->Mem->1 says 2.44 TI-84 Plus Silver edition but no boot code.

Maybe the 84 emulation is pre 2.55MP.
