This is my new acquisition:
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. :-(
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.
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 lnx
If 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
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.
I shudder to think how much this cost!!?
Great acquisition!

I actually didn't think at the time to reveal the internal 'guard' digits. - Meaning that the 5 is rounded up :-D
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,

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?

If you have liked that, you may also like this :-)
CLR ( 0 INV ln INV ln * ( 1 2 x<>t ( ( 3 * 4 ) +/- INV ln + 5 . 6 7 8 9 ) INV yx x<>t ) )
You are right:
