The Texas Instruments 92 Plus Programmable Scientific Calculator

The spirit of 99/4A lives on

If it weren't for the Internet, I would not know about the existence of TI programmable calculators. They do not seem to be sold here in Greece (Maybe in a few shops only in Athens and only the smaller models) while other brands (like CASIO) are widely known here.
Now there is nothing wrong with CASIO (I had many programmable CASIOs when I was a student and I currently own a CFX-9850Gb Plus) but as soon as I saw the TI-92 Plus I knew I had to have one. So I ordered one from an online shop in the U.S. - again the Internet to the rescue.

The TI-92 Plus is the most excellent scientific computer I've ever owned (and I've owned quite a few!) It is programmable in BASIC, has 192 Kb usable RAM and 768 Kb FLASH ROM for apps, can be connected to a PC using an interface cable and has a powerful Motorola 68000 CPU running at 16Mhz. It's more powerful than my original Atari STE! Needless to say, working with this machine reminds my strongly of my 99/4A.

Has a qwerty keyboard, a large high res LCD screen and many advanced functions. It is equipped with a Computer Algebra System (CAS) which can perform symbolic math.

For more details of TI-92 Plus and the upcoming upgrade Voyager 200, I suggest you visit TI's educational site

I am also planning to create a separate math site emphasizing in the use of programmable calculators that will feature math programs for the 92 plus. Stay tuned.
