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.
