I voted "Yes! For the worse!" because my friend and I opened up HIS TI-89, and tried overclocking it. Unfortunately, one of the surface-mounted capacitors was burnt away by the soldering iron, and the calc black-screened permanently.

ouch!

that has the potential to put a decent size dent in you budjet

Harsh! Not the brightest idea

I'd like to mod my calc sometime, but I've got too many other projects going on at the moment.

If I ever tried to mod my TI-84+ i would probably break the calc and most likely hurt myself in the process.

I like my calc how it is.

When I got my ti-89 the screen did not work so I took it apart and fixed it, and while I was in there I overclocked it. So for it was for the better :)

I'd love to overclock my 83+ Black Edition, but I don't want to risk breaking it until I get another calc.

i say do it because a new one costs like $50 on ebay

Does installing the Plus module in an HW1 TI-92 count?

5... that's old skool right there.

Hmm.. ive always wanted to have a backlit screen on my 83+ and 89 but im afraid that id do something weird and screw it up, since im horrible when playing with hardware... anyone wanna do it for me? hahaha.

I took one look at the screen of the 89, and it looks almost impossible to pull up the screen for a backlight. But the screen on an 83 will come off the motherboard and would be easy to backlight.

im not so sure, it looks to me like theres not even enough room inside for an led and to get even light you would need to install several

Yeah, I tried with my 86, and it was hard to fit LEDs in there and they didn't really light up the screen because of the angle.

I find it easier to use a booklight that can clip to the case or something.

My suggestion for backlighting would be to use an Electro-Luminescence panel. They're about as thick as paper, and bend easily. The only problem is they need an AC power source, not a DC.

at a place like radioshack ore something you can get an ac-dc or dc-ac converter for like 5-10 bucks or just find something that has it that you dont want anymore. the problem is that there about the size of your thumb =(

And don't they need a high voltage too? (I could be wrong) The backlight instructions I've seen online say to use an EL panel, but I tried the LEDs instead since I'm too lazy and too cheap to go out and buy one.

Get an EL inverter then. The online surplus shops are out of them right now, but they'll get more in probably. AllElectronics.com has a good selection of EL panels. You can actually take a scissor and cut a EL panel down to size. The inverters will usually take 5VDC and put out about 80VAC.

The inverters though are fairly large (the pcb is about the size of your thumb, as someone else said) and aren't terribly efficient.

Hmm...well I don't think I want to stick *anything* that puts out 80V inside my calc...there's too much possibility for damage.
