Hewlett Packard 48gx Graphic Calculator

I would like to say THE reference but I know that they are Pro TI & Pro HP users then I don't want to initiate the usual polemic :)

Anyway, this calculator is wonderful, you will find a huge amount of programs on Internet and I am sure that you will find the one suitable for your needs and activity.

This calculator still belongs to the HP glory's day. What I want to say that its construction is rock solid.

There are 3 different models:
- HP-48G : With 32Kb memory and no expansion slot,
- HP-48G+ : With 128Kb memory and no expansion slot,
- HP-48GX : With 128Kb memory and 2 expension slots.

You can find 2 versions of this calculator differentiated by the display. One version shows a blue writting on green display, the other shows a black writting on yellow display.

The 2 expansion slots can receive additional memory expansion cards or applications cards.

The 48 series has a built-in infrared communication system to exchange datas with other calculators or to access a HP82240A/B infrared thermal printer.

This series is the dign successor of the 48S & 48SX that initiated this generation of RPL (its programming language) calculators.

It is not necessary to put a lot of money on this calculator because it is a very common model that can be found used around $120 maximum with a pouch, the owner's manual and the quick reference guide if you want to take the time.

It's a great calculator for advanced math applications. One of the great features is the ability to stack the input figures for clarity. Also, the rpn feature becomes standard once you are accustomed to it, second nature. This particular calculator has been replaced with the 48gx, I believe, which is not as user friendly for my applications. I think hp should reconsider bringing this model back. It is an overall great calculator for almost any engineering/ scientific related equation as well as simple math computation.

This is the best Engineering calculator ever created hands down!!! HP should be ashamed of themselves for discontinuing this rock solid product. Obviously anything that requires true craftsmanship has been nixed for cheaper Chinese products.

My first purchase on ebay and it was fantastic. The item arrived much sooner than I had expected and in near mint condition. Better than the seller had described it. Much better than the one I am replacing it with. Great communication from the seller. Highly recommend seller and look forward to future purchases off of ebay.

Thank,

The HP 48GX is by far the best calculator ever made. HP has a great line of calculators but this one is bar none the best.

If your concidering a TI over a HP think again. You'll be sorry with a Texas Instrument!!!

I recently and forutnately won the bid for a replacement HP 48GX Calculator. I misplaced the unit I owned for approximately 12 years. After purchasing a newer TI unit, I found myself having to practicaly learn a new concept. While simoultaneously attending a Differential Equations course at school, I just did have the necessary time to learn a new machine. Upon, reaching a peak of frustration, I decided to search for a replacement. I found one here on eBay, bid on it, and won it. I understand the functions of the HP and became the proverbial "creature of habit". I now have and am in full use of the HP for my courses. I have been reacquainted and rely on my Old Friend.

It is just as I suspected. I've owned one before and like all the scientific features for an engineer

For nearly thirty years I've relied on Hewlett Packard calculators and I've loved every one. For me, Dave Packard and Bill Hewlett were to the "best generation" as Paul Allen and Bill Gates are to theirs. Times have changed; new (and vastly more expensive) products have come along, but since the HP calculator has always been the brains of my operation, I'm going to try to keep it that way.

it is exactly what i needed. i got what i wanted. Hewlett Packard HP 48gx Graphic Calculator thanks for the product

Easy access to funtions (after read the manual carefully)

Need patience, but once is understood you have the perfect tool for statistics, phisycs, obviusly if you are civil engineer this is the perfect match

It does everything the newer models do, but the build quality is WAY HIGHER! Yes it is slower than the lastest calculators, but so what. I actually love the fact that it has a 4 mhz cpu, because the new calculators chew up batteries in a couple of hours, this can run for months on a good set.

RPN is a bit different, but even a math moron like me can see it's virtues. Just be sure to buy a paper manual with your calculator. you're going to need it.

I have been using this same calculator (with a couple of identical replacements) for about 20 years. I have tried a few of the HP upgrades over the years, but always return to this calculator. I can't imagine what I will do if this one breaks and I can't find a replacement. In my opinion, it is the best calculator ever made.

Many HP Calculator collectors consider the HP 48 to be the pinnacle of HP design and quality. Although the color scheme was a controversial jump from the standard Blue/Orange/Brown, many Engineering students in the late 1990s moved to the top-end HP model because of the expansion cards, and powerful RPL programming capabilities.

The HP 48GX is third in a series of closely related calculators. The 48GX has 128k RAM and 2 Expansion Card slots. The related 48G+ has 128K of RAM also, but lacks the card slots. The 48G has only 32K of RAM, and like the 48g+ does not have any expansion capability. USE CAUTION buying or selling any of these three on ebay because the look and operate the same except for memory size and expansion. Look closely at the top- left and top-right hand sides of the FRONT of the calculator to tell the difference. The Model number (48GX/48G+/48G) will be on the top left hand side of the calculator.

This calculator is a must have for engineers. However, one should understand that to take full advantage one has to learn how to use it. The best time to learn to do this is to when you are in school where you can use it to solve the toughest problems you will ever face. Such as solving electrical circuits using the matrix function and polar quardinates. This can solve the problem with practically writing nothing down, without you would spend a long time iterating. Another good time is when you are practicing for you EIT or professional engineering license. Other than that, in the professional world, with the many software programs, spreadsheets, and other things, you probably wont use it to its full extent. But once you do you will never want to be without. All you HP users know what I am talking about. So in short, it you have the time and are forced to learn, get it. If you are new to the HP world and the 48 series, you may want to look at cheaper option, unless your rich then go for it and learn at your own pace.

In March of 2007, my vehicle was broken into and my 48GX was stolen. I had owned it since they first came on the market. Originally, I had an HP 11c which I had pruchased new. It ceased to work and I sent it to HP for repair. They said that they no longer made or repaired 11c's and would accept the 11c in trade on a new 48GX. That pretty much is the story.

When my 48GX was stolen in 2007, and no longer being serviced nor sold by HP, I turned to EBAY. Along with the calculator, a memory card, a cogo card, and a survey card was also in the case. I was able to turn all items into my insurance company and to replace them thru EBAY. I have been a practicing Civil Engineer for the last 42 years and the 48GX was like an old friend.

The item I received on EBAY was not in the same condition as my original calculator, however, it worked just as well. I like the service of EBAY.

I bought a used HP48G to supplement my HP28S. The 48G is faster than the 28S and can be repaired by an independent online service if it fails. The 28S is not repairable. The 48G is used at work (engineering) as I still prefer to work from a paper notebook using a calculator.

There is a wealth of application info for the 48 series on the web and the purchase price was reasonable (less than $70).

In the past Ive always wanted a 48G but could not justify the price given that the 28S met my needs. Now the price was right and I am very happy with my new(used) calculator.

Exactly what I expected. I received it exactly the way it was described. It is in great condition and works perfectly.

This calculator is in the almost the same condition as my personal calculator which I have protected as a cherished tool (it has not seen sun light).

the price was great i need the calculator for work i works great only problem is the port to the computer is missing a prong. still a good deal

This calculator has been discontiued by HP and is only available second hand. Surveyors who have invested in software written for the HP48GX depend on EBAY to replace calculators that no longer work. This is the second one I've bought.

This calculator, HP48GX, item is in excellent condition as are the manuals and the Sparcom Mechanical Engineering software PAC. The "black" LCD screen is beautiful! I can read it easily because of the excellent contrast. I purchased these items for three main reasons. 1. I really like the quality of the calculator and the excellent user manuals all from Hewlett Packard. 2. The Sparcom "Pocket Prefessional" Mechanical Engineering software PAC is exceptionally suited for my work with ease of use. 3. The black LCD. I can't say enough positive words to describe these items!I am excited to use all of this and I know I will enjoy these items for years to come! Russ

Product arrived in record speed & in excellent condition, exactly what we were looking for & we are very happy.
