hello to the group. first post for me too. Ed Von Essen here. Another 50g owner. Guy Teague asked about 49g+ / 50g differences. Another difference in the 50g is the ability to create sub-directories on the SD card. This is a small improvement but helpful if you are going to be storing a lot of data. I have a problem on the 49g+. I can't store any more data files on it and there is tons of memory going unused. I am getting a DISK FULL error. On a 64Meg SD card. If anyone needs to create file names automatically, I have the code to generate files names such as "S0054", "S0333", etc. and am willing to share it.
there is a problem with storing data on the 49g SD card. The file can not be overwritten. If you want to write more data to a file on an SD card, you must read in the data first, then modify it, then PURGE the file on the SD card, and then you
can store the updated data to that file name. This is OK until you are updating the contents of 10 to 20 or so data files and the battery goes south in the middle of the operation. Leaves one with a purged file and no good way to recover. There is a manual method to read the voltage. I would like to know if any one has a function to check battery power so that it can be tested in a program. Thanks for any help. ED

hello to the group. first post here. glad to have the resource.
i've used hp calculators since the hp-55 around 1975 or so. the quality deteriorated as the builds went to singapore and malaysia and then china. also, hp deteriorated as a company over two decades ending up with the present debacle and ceo-abuse.
i detested the 49g+ so much i've been using a ti89. but i saw the blister pack for the 50g while passing in a store and it looked so much better than the 49g i bought it on the spot without even comparing features. i was a little disappointed to note that the software and firmware innards aren't any different, but nearly everything else is an improvement.
one of the worst in a long list of things wrong with the 49g was the color scheme. i could barely see the characters. the 50g could have used a different color than white for both the primary and the alternate function, but at least i can read the characters.
i would have liked to have seen the 50g use 2 or 3 aa's instead of aaa's, but the battery life is so long, and now extended with usb use, that this hardly matters.
i would have liked a much better manual. i was reading through the users guide last night about the ISOL function and if i hadn't used hp calculators before i would have never got through the example. i never did figure out how to do it in algebraic mode.
i would have liked a sliding cover/stand like the ti-89 instead of the bulky, foul-smelling cheap vinyl one.
i really would have liked mac connection software as the ti89 has. ti really supports the mac. now that mac has a unix core there is no reason for hp (hp-ux anyone?) to not support the mac.
i'm ecstatic to have my equation library with the formula pics back!
but in spite of all my little carps, i'm glad to be back in the hp fold. i'll be asking you guys dumb questions to try to get back up to speed.

>Any information would be appreciated.- The keyboard of the 50g is much much better ;)
- When connected with the USB cable, the 50G is powered by the USB link and dont use the battery (excellent for flash rom for example)
- The 50G uses 4 AAA battery (only three battery in the 49G+)
- Difficult to have an real opinion about durability, but the 50g 'look and feel' is much better
- The 50g is very pleasant to use, the keyboard is really very good and the durability seems to be better.
- the 50g is the best calc that i never used ;)Gilles from France(french user group of 48-49-50G :)
