I've been researching the HP50G and will probably buy one tomorrow. My
current calculator is an HP49G. It's okay, but not great. Actually
haven't used it much for awhile. I used an HP41CX for years, really
loved it.
I will be using it strictly as a hobbyist, some programming, math, and
just playing around with it. Actually, my math is very rusty, so I
want to brush up some, and I figure it will be a lot more enjoyable if
I have a nice HP calculator.

The learning curve on the 50G is a little steep in my opinion,
my favorite calc of all time is the 15C, which I still have.

The 50g is an excellent machine, but the learning can be very, very steep. It's not hard to guess that many well-intentioned users will not get as far with it as they would like, for a variety of reasons, including the time necessary to become fluent with even relatively simple calculations and lack of a printed version of the detailed User's Guide. The 41cx, 42s and 15c were much better in this respect, though somewhat less capable. It's sad that these legacy machines have not been manufactured in many years and can be difficult to acquire.

The 35s is currently on the market, is reasonably quick to learn and more than adequate for casual and many advanced applications. The 35s sells for a reasonable price and, if you read all the way to the back of the Quick Start Guide, you will find a notation from HP, where they mention how to order a free printed copy of the essential and very detailed User's Guide. This Guide is on an included CD, but some users prefer a printed copy, which they can curl up with in front of a warm fire on a cold winter day.

That's what I'm doing too. The 50g is really nice, and surprisingly
fast with a lot of stuff that causes headaches when done manually. I
have a 48SX but seldom use it, because it is slow, and I don't like
the display. I've used TI graphing calculators. They're okay, I
suppose, but somehow seem unsophisticated, a bit dumbed down compared
to a good HP, and the lack of RPN is a serious impediment to routine
computations.

I wish HP would produce a good, small RPN scientific calculator. The
35S is a step in the right direction, but in some ways it seems a
little less convenient to use than some of their earlier calculators,
such as the magnificent 15C or 42S.

Yes, I really don't need or want algebraic entry. I'd much rather see
HP make another nice scientific calculator dedicated solely to RPN. I
loved my HP41CX. Wish I still had it.

I just got my new 50G out of the box and powered up. First thing I did
was switch it to RPN. So far, I really like it. I'm taking two weeks
of vacation starting tomorrow, so I should have some time to start
learning how to use it over the holidays.

Hi Jeff Enjoy your 50G great machine. When you get into programming, here's a web site that will be helpful.

Is a 2Gb card okay?

Re: [50g] Re: New member

2008-12-20 by Nancy Von Essen

Ed Von Essen here. Richard, the HP 49G+ with the original operating system got messed up when I tried a 1 Gig SD card. Had to reset it. It was happy with a 64 Meg card. And the 49G+ came up with a "disk full" error (file name table full) and there were still 55 Meg left on the SD card. I was storing data on the SD card only. The 50G will handle a larger SD card but will it handle more file names? I remember someone saying that file names were read in when one selected FILES. Well the answer to this problem is to write a file gathering program, in other words, stuff more data in a file. Of course, that means it's necessary to write a program to be able to retrieve the data you want, also. I was plotting investment data to see trends and the disk full error occurred after two years.

So figure out what you want to store and get the smallest SD (lowest cost) card for the job. And buy several as you go along. Using SD cards for specific purposes is recommended.

See, ask a simple question and see what happens?

I just purchased an HP 48Gii. Looks like a 49G but doesn't have a slot for an SD card.

Enjoy your 50G. It's a great machine and will keep you busy for hours. MC&HNY. Ed

On the 49G+ the max size SD card was 128mb. On both 49G+ and 50G the
max number of files is 512. I'm using a 1G SanDisk Ultra II (it was on
sale) and it works just fine in my 50G. Also, recommended is the
program SDfiler (for more options than the built-in Filer):
http://www.hpcalc.org/search.php?query=sdfiler
I like your idea about several different cards, but knowing me, they'd
be lost within six weeks. Will have to settle for one card that stays
in the calc and use subdirectories.

I need to clarify the max number of files. The max number of files +
folders is 512 in each directory on the SD card, so, depending on the
number of subdirectories, you can store thousands of files on that
little card.

This is not a 49/50g restriction. According to Wikipedia[1] "For
historical reasons, FAT12 and FAT16 media generally use 512 root
directory entries on non-floppy media."

Since every HP variable and Directory are a FAT16 file (as seen on a
computer) they are restricted to a max. number of 512.

I'll try messing around with mkdosfs a bit to see whether the calc
will tolerate more.

On the memory card size part of this.

2Gig did not work.

Welcome new member you may contract me directly at the following, if you like, at the following ehoe@... I also have spent endless hours

on the HP41cv and the 75C(basic and selfcompilier)

Your 2Gig I think should be reformated in FAT32 but

some will say that FAT is the only way when downloading a new ROM or upgrading the equation

libraries. I have never had any luck with the serial

transfer on the HP50g but it was great for 10 years

on the hp48g/gx I think the SD chip method is the future. Good luck to you. Cheers for 2009
