How will compete hp-prime with TI-Innovator project?

[debrouxl]

BTW, the TI-Innovator is derived from one of the MSP432 Launchpad boards, which are much cheaper. Therefore, one can leverage a subset of the TI-Innovator features, e.g. light sensor and buzzer are missing out of the box, at a fraction of the price tag - less than $15 - by reflashing the appropriate Launchpad model with the TI-Innovator firmware. The Launchpad has a micro-USB interface while the calculator has a mini-USB one, so one needs to buy one or more adapter cables.
This is not theoretical, critor and/or Adriweb have tested it - I'm basically summarizing https://tiplanet.org/forum/viewtopic.php?f=49&t=18947 here.
