TI-88 - lgomez - 09-22-2012
This is my new acquisition:
Re: TI-88 - Marcus von Cube, Germany - 09-22-2012
Congratulations!
Does it have a bouncy keyboard like the one I had in my hands recently?
Sadly, the keyboard of this device is as bad as it can be. :-(
Re: TI-88 - lgomez - 09-22-2012
Yes. It remeber me the TI-57 LCD owned by a school friend in the early eighties. The keyboard of my TI-57 was infinitely better than the keyboard of the TI-57 LCD and the TI-88.
Re: TI-88 - Marcus von Cube, Germany - 09-22-2012
It's a real pity. The machine seems very capable.

If you still have your TI-57, try this keystroke sequence:
CLR 1 +/- + 2 + ( 3 x2 x2 x2 + . 4 5 6 7 8 9 0 lnx ) 1/x + 2nd pi 1/x = INV lnx INV lnxIf the keys are not bouncing then you might get the answer to some important questions :-)

My TI-66 gives the answer 41.99999995 LOL ;-)

Close enough... regarding to the 'unknown' question. 8^D
Re: TI-88 - Gerson W. Barbosa - 09-22-2012
My TI-57 gives 42.000000022, but because it can display only eight significant digits the result is rounded to 42. The actual 12-digit answer is 41.9999999486, which quite agrees with your TI-66.
Re: TI-88 - mr-scorpio - 09-22-2012
I shudder to think how much this cost!!?
Great acquisition!

Re: TI-88 - mr-scorpio - 09-22-2012
I actually didn't think at the time to reveal the internal 'guard' digits. - Meaning that the 5 is rounded up :-D
Re: TI-88 - QUESTIONS YOU DON'T ASK... - Joerg Woerner - 09-22-2012
You never ask a girl about her age and you NEVER ask a TI-88 owner what she or he paid for it.
Rule of thumb: If you have to ask for the price - you can't afford it ;-))
Cheers,
Joerg
Re: TI-88 - Serial Number - lgomez - 09-23-2012

Re: TI-88 - Eddie W. Shore - 09-24-2012
I managed to get 41.999999995 on my TI-65.
Bummed to see that the TI-88's keyboard is not good. Does it run a complete operator system?
