The later model HP-29C does not respond to a short key-press, the program will not be interrupted, instead it needs a long key-hold-down until the pause ends to stop program execution.

Strange; the 19C is interrupted by a brief keystroke, like the 25. That's an unexpected difference between the 19C and 29C.
