Older TI Graphing Calculator

Grandfather of the Ti84 Tsubasa posted a photo of. I have Ti's first graphing calculator, the TI81.

These things have definitely evolved since the beginning. My Ti81 has no link port, 2kb of memory and a 2mhz Z80 processor. The Ti84 still uses a Z80 processor but at a higher speed, has a USB port and much more memory. Both have the same screen resolution and run off four AAA batteries.

  1. I didn't know that Z80 was used in TI-81 and TI-84. No wonder Gameboy games can be run on the TI-84. :)
