I became one of the 15c collecting Crowd

Thanks for the links to previous discussions.

I tried integrating e^(x^3) , x= 0 to 6, on the hp15C CE and Touch 15i emulator at full speed. It did indeed converge, using display SCI 6, which is an many digits as can be displayed directly. The calculator got there in 17 seconds, and the emulator in about 2 seconds. With SCI 5 it was about 7sec and 1sec respectively.

Exactly the same value was produced by the calculator and emulator. In SCI 6:

5.963 938 x 10^91

From the previous discussions, that seems like a credible result. Wolfram Alpha thinks so too:
   

Actually I find it amazing and impressive that this works!
