Today I got a 1990s vintage calculator for practically free. I found a dollar on the ground and then minutes later, I go inside a thrift store and buy a TI 83 for a dollar. Supposedly this model was the high end for TI at the time of it's release in 1997. It shares in common with other models such as the Ti82, 83 and 85 a 6mhz Zilog Z80 cpu. The screen has the same horizontal resolution as a Ti83 but is wider and has higher vertical resolution. You can also type in lowercase letters on this thing. Overall a pretty nice calculator and it has a high end feel to it but compared to models you can buy today, it feels a little past it's prime.
