I needed a T6 Torx to disassemble. I had a TI 84 quit working. I ordered a used one on eBay, but the case had a name on the back and showed a lot of wear. I disassembled both to put the parts of one case into the other. Works fine.

Does anyone know if you can buy and replace the screen on a Ti-84 +. I work for a school district and we have 120 of them 5 years old. Some of the screens have the lcd's busted by kids. Any thoughts from anyone?

Thanks for the instructions! This helped me disassemble my TI-84 Plus Silver Edition and turn it into a Gold Edition! The outcome can be seen here.

im thinking about disassembling my ti-84 so I can custom paint it a bit...will the calculator still function properly after disassembly? I disassembled my ipod mini once and it never worked again...lol

would it be possible to swap the front cover for a TI84 Plus one? to allow for faceplate swaps.

Okay, so funny story. A week after I posted this Instructables a classmate came up to me and asked to see my calculator, he looked at it and said "I think we switched calculators during our last quiz" I looked at the one he had and sure enough there were all the programs I thought I had lost when I removed the backup battery on the one that I took apart. I took apart a classmates calculator thinking it was my own :) lol... I still laugh about it. Any way I had to share it...

why would you disassemble your calculator ?

Feb 18, 2008. 5:46 PMMadManMike (author) says:

Do you need an excuse? Like others have said my keys were sticky after spilling a mocha on it :) But I also wanted to take a look at the mainboard, I am thinking of trying to build an external display for it. -Mike
