It's all because of the highly successful

having needed anything more advanced than square
root on the SAT; the G'RE doesn't allow calculators at
all). As a result, TI can get away with selling the same
machine they were selling 10 years ago (with minor tweaks)
for the same price as 10 years ago.
45 years ago, for the SATs, Kurtas were not permitted,
although that was NOT explicitly stated in the rules.
Slide rules were explicitly forbidden.
However, they permitted, and ENCOURAGED! bringing scratch paper,
even graph paper!
After MY group took the SATs,
they changed the rules banning your own scratch paper,
in order to stop "origami with logarithmic graph paper"
