I overclocked my calculator. It got my ti 86 to go 18 Mhz. Althought 1 week later the procceser fried out and i ruined a good ti 86 (oh well it was from ebay...)

I *attempted* to overclock my TI-82, I didnt even change the capacitor, I just opened it, and my link port was gone... so now I cant have asm games or download games, so I had a lot of time, and make some kick-@$$ BASIC games and utils... well, the other day in class, I decided to swipe my TI-82 with that kid next to me... he hasnt noticed yet, and I dont think he will (heh). and then yesterday I just took my original back, and he still hasnt noticed.. so I can finally play asm games and continue writing asm stuff... so my point is, dont overclock it, or even open it, cause it will end up screwed like mine!

Ahhh, the ethics of overclocking...
Here is a list of why I attempted to overclock my old TI-85.
1. To see if I could do it.
2. To make it graph and solve faster. Occasionaly, during Calculus, I was unable to finish a LONG test due to the calcs speed. Just a few more seconds, and I'd have been ok.
3. To see if I could do it.
4. Game faster? (turns out to be a bad thing.)
5. To see if I could do it.
6. To see if I could do it.
7. To have the fastest calc in the school. (and I did...)

Now, here is what happened. I successfully removed the Capicitor. The calc worked. I tried to hook up a speed switch. Uhh ohh. Solder spread to the other pins of the processor. It dosn't work. I tried several times to remove the solder, but I still can't seem to get it all. Wonder if I shorted something... Ohh well. After two years of loyal service, my calc died. Now I have an 86, and I'm out some cash. Oh well, I have a job, and I'm paid fairly well for what I do. (MIS department gopher. Hey, ghost this. Fix my Mouse!)
I had the calc working at school while overclocked for two days. Graphs went unbeliveably fast. Solver was faster yet. And as far as games go, most were unplayable. Try playing pac-man at 3 to 4x the normal speed. Hence, why I wanted the switch. <sniffel> RIP old 85. I still feel bad about that. </sniffel>

As an interesting side-note, If you've got a bad flu and you're so dizy and out of it that you grip the soldering iron by the wrong end, after you fix your hand up, don't try to convince yourself that you can still concentrate enough to modify your calculator. <BR><BR>
Not that I would know or anything...

I hooked my calc up to my P2 and have it parallel processing just great. =-)

I have not overclocked my calculator but I overclocked my PCs CPU once. An AMD Duron 800 @ 1000MHz but I gone back to 800MHz.
