TI59 Diagnostic forensics

[Maximilian Hohmann]

Hello!

Very interesting. My Ti59 (bought new in 1978...) did not come with that card.

What I fail to understand however is why such a complicated calculation must be done to check if the calculator is working. It does not have a seperate floating point unit as far as I know, just a single CPU. So if it is able to come up with the correct result for "1+1" it should be good for everything else, shouldn't it?

Regards
