HP Prime: Firmware Update (13865, date 2018.07.06)

HP Prime:  Firmware Update (13865, date 2018.07.06)

There is a new update to the HP Prime firmware.  The new version is 13865. 

You can find the file and details here:

Details and file: 

I haven’t had much chance to work with the new firmware, however according to the release information, some of the highlights are:

* There is a new red indicator when the HP Prime’s power reaches below 10%.

* All integrals in HOME mode will calculate numerical results.  Previously results are returned in either numerical or exact answers.  Exact answers will still be provided in CAS mode.

* You can control the amount of time until the HP Prime dims its screen.  The screen is dimmed when you do nothing on the calculator after a set amount of time.  The time is set in milliseconds as a base integer (30,000 in decimal or 7530_16 in hexadecimal).  The variable is TDim found in the Vars-Setting menu. 

* The command EVAL is said to now help INPUT with local variables.  I haven’t played around with this yet. 

* Updated CAS and improvements

As a note, there the HP Prime now gets a new processor G2.   To find out what hardware version you have, press [Help], press the soft key (Tree), scroll up, select About HP Prime.  I have hardware revision C.  The threads on the MoHPC site goes into more details.  The reason why I mention this is if you have trouble updating your HP Prime, the firmware files may need to be in a new folder.  The folder is:

Hardware C (and I’m assuming this will work for A):
(your drive) \HP Connectivity Kit\Firmware\PrimeG1

Thank you to HP and HP Museum of Calculators! 

Happy Computing,

  1. Where can this HP Prime with 2018 be purchased? Amazon doesn't seem to carry it. Nor Best Buy.

    1. Unfortunately, your guess is as good as mine. I haven't seen any of the G2 Primes in stores (Best Buy, Fry's) nor on American websites online. Even the HP website side it was sold out other day. Eddie
