I bought a cheap scientific calculator for math class. When I tried to multiply .5 by .5 it gave a long irrational number instead of .25. then I had to try to explain to the store clerk why that was wrong before they would accept the return
First gen Pentium seems like it would be overkill for a scientific calculator but I guess they had to offload those chips somehow.
The ti-84 plus is based on the zilog z80. From 1976. The calculator is still being made, and still costs $100.
