HOWTO overclock a Texas Instruments

04/17/2005 07:20 PM

Cory Doctorow: My dad, a high-school math teacher, loved the Texas Instruments graphing calculators as an instructional tool. Nevermind the early IR hacks that let students beam test-answers back and forth during exams, the important thing was how much you could learn by having ready access to a graphing calculator while doing quadratics and the like.

Of course, those TI calculators were a little on the slow side. The intarweb comes to the rescue: with just a little overclocking know how, you can bring the older machines up to a blazing 12MHz and the top-line beasties all the way up to 20MHz!

Curently, the TI-81, TI-82, TI-83, TI-85, TI-86, TI-89, TI-92,a nd TI-92 Plus can be accelerated. The 81, 85 and 86 can be accelerated to approximately 2-3x their normal speed, about 18 MHz. The TI-82 and TI-83 can also be accelerated to about 1.5-2x normal speed. They only about double their speed to around 12 MHz. The TI-89 and 92 can be accelerated to around 20 MHz!

Overclock Your TI Calculator


Overclock Your TI Calculator 04/18/2005 10:04 AM

redcase.jpgI was the coolest kid in PreCalc, having splurged and bought the six colored TI-83+ calculator cases offered on their web site. (True story.) Now you can rice out your TI from the inside, overclocking your calculator with a quick trip to Radio Shack, a soldering iron and a basic comprehension of the term "will void your warranty." Overclocking TIs is nothing new of course, but we believe each new generation deserves to run TI-Snake and Drug Wars at its very quickest. Richfiles has full step-by-step instructions and pictures for every model from the TI-81 to the TI-92.
