Man, those cell phones were so massive in the 90's

Only prob is there's nothing to scale the calc to.

Then you ask someone who remembers it's a Texas Instruments TI-81 and measured about 3.3 inches X 7 inches

That was the grail of all graphing calcs

Actually, I still do have mine SOMEWHERE in the house. That mother was expensive as hell....$200 was a LOT for a calculator if you didn't have a full-time job. It's saving grace was that it was surprisingly miserly when it came to consumption of the 4 AA batteries.

The REAL pisser is that I had to drop out of college, so I never used it to its full potential. :(
