  • I own a Yamaha PSR E403. This series is a lower end class of synthetizer/arranger keyboards targeted towards novice players. Mine also has an identical UI to the one presented here. I wonder if the hack would work on it as well, being a similar model.

    My better keyboard is a Yamaha CP88 which is a lot more modern and has updatable firmware. I poked a bit with the update package using binwalk and as far as I could tell it’s not encrypted, and runs some version of QNX. My hacking skills aren’t as good, but I wonder if that one has similar exploits.


  • In the US, the purpose of incarceration is cheap slave labor, which is why oligarchs like it this way. Can’t have that if inmates have rights and are allowed to have non-slave jobs.

    Prison workers in the US are generally exempt from workers’ rights and occupational safety protections, including when seriously injured or killed.[43][39] Often times, inmates that are often overworked through penal labor do not receive any proper education or opportunities of “rehabilitation” to maximize profits off the cheap labor produced.[44] Many incarcerated workers also struggle to purchase basic necessities as prices of goods continue to soar, meanwhile prison wages continue to stay the same.
