Texas Instruments TI-92 II - great find !!
Texas TI-92 II (Advanced Symbolic Scientific Graphic will full QWERTY keyboard).

So I just purchased this for 20 UK pounds ($25 US or so) and was described as "new" by the seller, I had my doubts given they were produced from 1996 onwards (the TI-92 II from 1996 to 1998), but even used was a good price.

It arrived, and amazingly the device was brand spanking new boxed, and had never been opened or used.

Date code indicated manufactured Feb 1998.

It always surprises me when stuff 20-30 years old or more comes onto the market and is brand new and boxed, one wonders where this stuff has been the last few decades.

Probably in warehouses gathering dust?

This one though still had a sticker on it indicating price of 249.99 UK pounds (then around $450 USD) !! So must have at least made the store...

Nice find Smile

But try and find yourself a TI-92 Plus. The screen is so much better.

Yes, I heard this, and the "TI-92 II" display is almost as bad as the 48S/SX ))))

Usable.. just... to think back in the day we accepted this as normal, in good brightness usable, even slightly dim and it is terrible, the 2004 TI-89 Titanium I have is a little better, and the 2010 Casio FX 9750 GII (mid range graphing) is like another world (beautiful bright LCD) as is the HP-50G (almost as good).

Mostly use the HP-28S however and for a 1988 calculator the contrast is usable even in dimmer light!

The TI-92 is an underrated calculator. I prefer that screen to the tiny TI-89's screen.

The screen of the TI-92 and the TI-92 II is atrocious. While the font may be microsocopic on the TI-89, the added contrast makes it arguably more readable than that of the 92/92II. I need glasses to read either one so I'll take the good contrast over the increased size Smile

Only the TI-92+ and the Voyage 200 have the best of both worlds: larger screen and acceptable contrast.

I might do a comparison of all the MC68k-based TIs at some point.

Hello!

Yes, sometimes one can only wonder... On the other hand, some day in the future someone will find a sealed unopened box with an HP-15C Limited Edition inside in my estate and wonder why I never used that wonderful machine.
Some years back I also found a boxed and seemingly unused Ti-92 (not the II or + veriants) on the flea market. The seller (a kind of professional flea-market trader) could not remember where he had gotten it from.

I also liked the Ti-92 quite a lot until I gut a Voyage 200. As others have already said, the display is so much better. It is also much more powerful and occupies only 1/3 of the volume of the 92.

Regards
Max

Yeah, the Voyage 200 is the best option. The TI-89 screen and keyboard layout are awful, and the Voyage 200 has more flash RAM and a real-time clock when compared to the 92 Plus.

If I recall correctly, the TI-92 Plus and the TI-89 are the same thing except for the format. Similarly, the Voyage 200 and Ti-89 Titanium are equivalent devices.

You are correct. Aside from size, number of pixels, memory, CPU speed, real-time clock, and presence of USB, they are essentially the same.

I know it SOUNDS like a lot of differences, but it's mostly auxiliary things. You could pick any one of them up, and they would work the same. Smile
