I was looking up the price for a TI-92 and I found how to overclock several TI calculators. I never knew you could do this. There were times last year when it took several minutes to process a calculation. I could have used it.

This is cool. Havent tried it yet. Had to spread the news.

    Carefull with this, as you'll suck batteries dry pretty quick. Thats why TI never had these calcs running at that speed in the first place.

    Its pretty cool that they are using a CPU that came out in 1974 and is still in production, and it happens to be a Zilog Z80. I'm sure the chip isn't nearly as big as it was then. But anyway, it is fairly interesting.
