The TI-86? It's actually a beast of a calculator when it comes to Linear Algebra. It handles complex matricies better than any other TI calculator with the exception of the Nspire CX and CX II. That said, I have never used one either, lending credence to your observation. I have passed up several auctions for them since the TI-8X line of calculators is not one that I actively collect.
It sure could play some surprisingly advanced games lol someone got a fair bit of ALTTP on there if memory serves. Or at least some mainline Zelda game
