Ran out of batteries and got now charger, and I'm not willing to make a makeshift cable, I'm a software guy not hardware. 
And you don't have any micro usb cable sitting around? I can count on 1 hand the times I've used the "official" charger. It will charge just as well from any usb port...

It breaks file transfer between the emulator and calc,
One of the issues prior with the emulator was that you couldn't tell where the communication was going. There is a new windows menu called "Connect To" that lets you select wit which unit you are trying to communicate. Have you selected your USB unit?

Do you know if the sequence problem I've reported to you
There has been no changes to the sequence application to support 0 based sequences in this update. Will this update the simulator too ? I still have version 2013 8 13 Rev.5106, and no update required. Will the new features be usable though ?
Using the check for update from the virtual calc will find the update. If you'd prefer, just downloading the new installer directly and running it will also do the same thing.

First updates are live. The check for update in the emulator/connkit should find them. If not for some reason (usually due to proxy or other funky network things on your end, use ftp.hp.com/pub/calculators/Prime/) Many thanks to people who've reported issues here in this forum or in other spots. You may notice some direct called out items that go back to a specific post. Even though we consider this a "bugfix" release with no empasis on new features, there are still about 2-3 times or more new capabilities compared with the recent "2.0" casio update I saw...  Items of interest for many here might be the new TRIANGLE and FILLPOLY commands. The TRIANGLE command allows you to pass a large matrix of vertices, colors, rotation data, and z-clipping info (solid colors only at the moment). This means you can draw complicated 3D shapes in basically a single user function call! Here's an image of a 3D graph drawn with one single draw command. Oh, and did I mention I could rotate it at about 20-25 FPS with no optimizations yet? :-D  Who's going to get on that X-Wing game.... ?  HP Prime – Release Notes

Strangely, the HP-39gII firmware is not in ftp://ftp.hp.com/pub/calculators/39gII .
The 39gII firmware comes packaged with the installer. It is not a separate download. So it actually is already on the computer already in the connkit install dir.

This is not an official release, since HP did not post it on their website yet, but I think I know why, because it doesn't install at all: I'm guessing going to the hp ftp site would be better... ftp://ftp.hp.com/pub/calculators/39gII/ (this is the location the automatic check for update will check to try and grab updates) The reason why it doesn't install most likely is related to the the overwriting problem you mentioned. I am guessing that on some systems having the new prime connkit (which was installed to the same directory) probably is causing issues. Just manually uninstall the old 39gII one first and it will then install fine I expect. This newer 39gII one will install to a different directory so there should be no conflicts. Cough, cough, my French is very lousy, but shouldn't it be "Error at file 'reading' level"? Doubt it. Seems to me the problem is conflicts in the original msi backup files from the first install. It's a standard windows message/translation that comes with install shield so I am guessing it is correct with the sheer number of eyes that have looked at that message before. As to what will be in that connkit - basically nothing different. The firmware for the calculator has some minor CAS fixes and sepcifically fixes around matrices. However, it is not much of a change nor will it radically improve the system.

I wonder if such compression would be fast enough for calcs?
Dunno about this particular algo, but as an interesting side note we gained about 2.5MB of size with the internal calc on Prime by using a huffman encoding for that text.

Well I never got anything... Except a lot of complaints I guess.

It makes sense to have a system set of variables that can be transferred from program to program, but it would also be nice to have local-program variables. It seems like having both should be an option.
You do have local variables (local in the function, and local to the whole file).
...8+3*i=:C1 Error:Invalid input
Change that to a Z<N> which is the complex and it will work. You are missing the rest of it which is "why is my list variable not a list?" The vast majority of users want to know that certain variables will ALWAYS be a certain type. L1 is a list. Always a list. L1 being a single number messes them up. Why is my X a matrix? Why isn't my matrix a matrix? They associate certain variables as being a certain type. I agree that the error messages need serious work though.

Advanced users have no problems with "i am in charge of creating a variable". However, we have very strong feedback from lower end users and educators that having a set of predefined variables is very important and useful to them for many reasons. Prime in its first release is not targeted directly at high end users. What was and wasn't in the first release was not targeted at the top 1% of users. If that messes up "your workflow" as was posted in that thread, and even the fact that someone is posting about calculators, pretty much by definition means they fall in that tiny power user minority. Wow, if PPL is interpreted, then I guess that might explain why it's so fast lol.
Interpeted mean *slower*, not faster unless something is strangely wrong. What happens is that since the compiler is so fast, the first time you use it then things are compiled for execution and will remain around until a power cycle.

INT is a cas command (which isn't even supposed to be in there actually as it conflicts with "int" the integration command). IP (integer part) is what you are looking for I suspect. That might make a "small" difference...
RANDOM(255) would also give you the same thing there and be sightly quicker.
Basically, any input that requires a number will correctly pull from reals, integers, or complexes.

Well, us HP users have traditionally been the "nuts" with far too much enthusiasm for our own good. :-) He also has some other seriously awesome posters as well. I have the curta one hanging above my desk at work (next to the hp calc one), and the telephone history one outside in the aisle.

Very nice! I will definitely be saving this to use every time someone comes to me asking "when was <insert_unit> unit launched?". It will be quite useful. I can already do that with my vcalc.net HP calculator poster created by Rick Furr, but this will be helpful for the other "nameless" company's units. Seriously, if you consider yourself a calculator fan (of any calculator), you should order one of these posters. They are amazing and quite cheap. Very, very impressive and I wholly recommend them. Has introduct and discontinuance dates, code names, features, and all sorts of great stuff. We have them hanging all over the wall over here at HP because they've been so darn helpful. From the site: After 7 year from the publication of the original HP Calculator poster and over 1 year in the making, I am proud to introduce the Calculators of HP Poster #2 for all HP fans. This poster shows every HP calculator made starting with the famous HP-35. It now includes pictures of 115 HP calculators and 20 peripherals made through 2012.
Each calculator is displayed with it's production start and end date, and the project codename. Lots of new information has been added including dates and code names for more of the HP41 accessories, HP-IL devices and printers.

Does anyone have any clue where that idea came from? I've been unable to track it down myself after some time looking.

but I'm outputting verbatim the data part of the packets produced by the calculator (or so I think, at least  ).
I'm guessing then that you haven't figured out our little "hack". Basically, PNG has no definition for a 16bit per pixel (color) encoding. Since the calculator is currently running using an RGBt 5551, you have 16 bits per pixel. However, there *is* a defined 16bit per pixel greyscale in the png standard. Since PNG is lossless... Convert your values coming out from 5551 to a 8888 or similar and I suspect it will look a bit better. :-) As for the "8 minutes to enumerate", I've never been able to see anything like this. An empty calculator usually takes a few seconds - even over wireless which is slower. How much stuff is in your system? How long does it take an empty calc? // CCITT CRC-16 look-up table (X^16+X^12+X^5+1) (this looks like a good place to look at:http://www.embeddedrelated.com/groups/msp430/show/29689.php) Initialized the crc bytes to 0 at start (yeah - dumb, caught too late to mess with). Also, looks like it might be including the first byte, but using the "length" value which does not include the first 6. (so first 6 bytes are included and last 6 are not). unsigned short crc = 0;
while (len--)
{
crc = crc16_tab[(crc >> 8) ^ *buffer++] ^ (crc << 8);
}
