Thank you Michael!
This release, providing "MEMORY CLEAR" instead of "Pr Error" is definitely a very good sign of better "User Experience" VS "100% compatibility".
I am confident to see more in the next releases 😀, and one day maybe the Graal = alpha instrictions vs opcodes 👍
Take care,
Sincèrement, Sincerely, 73,

2xDM15L, DM41L, DM42 SN#00855 (+one lost during shipping), DM41X #00707
TI-89 titanium, CASIO fx-cg50 (to play with micropython)

Hi Michael,

Well after continually pressing the Program button on the firmware tool and resetting the calculator, I finally got the calculator update to V32 and get a MEMORY CLEAR. This is not an easy process despite the the very good documentation, or I'm doing something really wrong.

Thanks for the update.

My Voyager DMs are all tricky. Some combination of the program and reset will usually get the update tool to start sending. It varies.

DM15, DM15L: 11069 / DM16. DM16L: 02001 / DM41, DM41L: 00859
DM41X: 00036
DM42: 3108

Hello Michael,

Thanks for the new version.
Update via Linux Mint was a breeze.
Have a nice week-end,
