HP 48GX Graphic Calculator

This is the last really great HP calc that is pure RPN. I've been a fan of RPN since my first HP (a 35) in 1974, and dislike any other interface format for a handheld device. Sure, the newer HPs (HP 49g, 49g+, 50g) have slightly more capability, but the 48gx has at least as much capability as most scientific and engineering professionals would ever use. Fortunately, these newer models also have RPN, as well as algebraic interface options, but they lack the big "Enter" key that we RPN fans have come to love.

If you've never tried it, get an HP with RPN capability and use it (in RPN mode, if there's also an algebraic option) for a week. You're almost certain to be converted by RPN's efficiency and ease of use. If you're fortunate enough to find a 48gx at a reasonable price, you'll soon be hooked on that big "Enter" key that seems to be located in exactly the right place!

When I used this calculator during my semester in Trigonometry consistently had my answers quicker than anyone else fumbling with their TI-83's. This is due to the RPN input style. Even better now, and in good quality is the HP-50g with which you can use it in Algebra mode or RPN. But, the older 48gx has the best quality as far as solidness and key function.

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.

I'm not sure why HP quit making these calculators. They are still the best for what they do. I use them for field engineering & construction lay-out, and barely scratch the surface of what my calculator can do. I buy all the reasonably priced 48GX calculators I can find, so if you have one for sale, let me know...

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
