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

Try integrating from x = 5 to x = 6 and compare the results and times. The HP-15C app by HP gives the answers instantly (too bad the blinking display bug still persists after all those years).
