Grobs on HP39G



  • 1. Jo and his sense (or lack therof) of humour
    I have to admit that reading Jo's messages make me laugh. Unfortunately, I feel sorry for the poor cat. Oh well, at least every NG has at least one comedian.
  • 2. Dream?...Nightmare?
    I could have sworn I received an email from hp stating that there was soon to be a ROM update that would fix the alarms. I cannot find it, and I REALLY think it was a dream. Anyone know of any ROM upgrades beyond 1.23, or are we stuck with sucky alarms? Scott
  • 3. PSI(1,i) returns "Bad Argument Value"
    Hello, I was trying to compare the results of PSI(n,x) with those from the polygamma function I wrote for the 68k. PSI(1,i) returns "Bad Argument Value" for some reason (after prompting to change to complex mode). Am I doing something wrong? Thanks, Bhuvanesh.
  • 4. HP49g+: INTVX gives undefined name
    This is driving me crazy. I can't do a simple Integral like INTVX(x^2), all I get is error: undefined name. Even just using INTVX(X) returns the same error. Any idea how I can get my 49g+ to do integrals, or what I am doing wrong?

Grobs on HP39G

Postby chris_morris » Sat, 18 Oct 2003 07:00:40 GMT

I am new to Grobs for my HP39G.  Using XNVIEW to create a .gro from a
.jpg, and then GRS64 to create the Aplet from that; how do I (first?)
reduce the ~80K jpg (ex camera) down to 131x64 pixels?
                 many thanks,

1.grobs on the 49g

Hi all,

I tried to get some hp48 grobs from the website to work on
my 49g+.

As I'm loading them (using conn4x) I get a warning message: "C:\hp
calculator\file.gro is a .gro file and does not match the ccalculator.
This may damage the calculator contents. Do you wish to continue..."

Also, once the files are on the hp49g+ they show up as string files.

How can I get my hp to recognize that they are grob files?


2.How to make Grobs?


How do you make grobs?  Can i make equationd in say Mathtype equation writer 
and export them to a grob to display on the 49G+?  just for reference notes.

I currently use WinHP 3.7 &  TVG for adding written notes, is there a better 
method that allows for equations or diagrams to be added aswell?

thanks in advance


3.GROBS question & help

I know this has been asked a bunch before, but I looked through all
the posts and couldn't find the answers.
I converted a BPM to a GG file using bmp2hpgg.  I loaded them into my
SD card. Pulled one up on the stack, & went through the prg menu,
trying both PICT   & GRPB commands.  I've also tried PVIEW. So, what
the heck am I missing that will allow me to simply view the graphic?
Does it need to be embedded in a document? I tried that route with
WinHP.  I wish to be able to simply view the graphics independant of
any other files if possible.


HP Rules!    ;)
