This video demonstrates an easy way of doubling the speed of a HP 42S programmable calculator via a configuration change only.

The default speed is demonstrated by executing BEEP and a simple loop program. The calculator speed is then doubled and the speed increase is demonstrated using the same commands.

Note, This procedure was tested multiple times on ROM version A and C calculators with no issues, however, please proceed at your own risk on your own calculator (for example memory could be lost etc).
