It's a very common practice, not just in computers. Many digital oscilloscopes (and probably other instruments too) can be hacked by just editing a file or flashing a new firmware. The purpose in scopes is making them behave as more expensive models with much higher bandwidth, which means that faster ADCs and circuitry is already there, but not used to its full potential so that the device can be placed in a lower market segment and sold cheaply. https://nyctomachia.wordpress.com/2018/09/02/riglol-unlock-extra-features-on-rigol-oscilloscopes/ https://nyctomachia.wordpress.com/2018/09/02/riglol-unlock-e... https://www.makermatrix.com/blog/hacking-the-siglent-1104x-e-oscilloscope/ https://www.makermatrix.com/blog/hacking-the-siglent-1104x-e... ..etc.
