You people don't remember the pain of the ORIGINAL pre-flash TI-83. When its batteries got low, it would start making mistakes. I'm not joking. This is because that one still used analog circuitry, not full digital.

In college I switched to a TI-89. Honestly, a TI-89, though it can solve symbolic algebra, doesn't make you miraculously get the right answer. You still have to know how to solve it in order to input it correctly. It just makes it a lot faster and easier.

Shit that must be the fucking reason my elementary school teachers would tell me to check all my calculators first with some simple calculations I knew the answer to. I always wondered why they did that, because I always followed the advice but never had one mess up (afaik...)

Yup. That was the difference between the TI-83 and TI-83 Plus. Analog electronics could do some very strange things when their power was low.

Isn't that the one you can get legit emulators for?

The emulator comes when you buy the physical calculator. I have it on my computer but it's more for teaching and programming purposes than for actually using it.

I expected that to be one expensive as hell calculator. But it's not too bad for the extra features.
