Now you can have your own personal “computer”!

Introducing: The HP-65

… the first and only fully-programmable pocket calculator that you can use to solve extremely complex, lengthy or repetitive problems in seconds --- anywhere… anytime!

Imagine a “computer” that fits in your pocket! Imagine that it’s no bigger than --- and looks very much like --- an ordinary pocket calculator … but doesn’t cost very much more! Now imagine this miniature marvel in your hands, as you try it out for 15 days and cut your problem-solving time down to seconds!

But why imagine? Now --- thanks to Hewlett-Packard’s newest state-of-the-art technology --- there is a pocket-sized “computer” … the HP-65!

Just like a computer, it’s fully programmable. And it uses computer logic to solve even extremely complex, lengthy or repetitive problems in seconds --- anywhere, anytime --- at the touch of a few keys!

No, this personal “computer” doesn’t use tiny little reels of tape or miniature keypunch cards. It uses small (approximately ½ inch x 3 inch) magnetic cards. Each card can store a program --- a sequence of keystrokes --- up to 100 steps long. (And, if additional steps are needed to handle un unusually long program, you can do it in stages.)

To insert a program into the HP-65, just run a pre-recorded program card through it. All it takes is two seconds! The information from the card is duplicated in the HP-65’s program memory, where it remains for as long as you leave your personal “computer” turned on.

To solve a problem, just feed in the known data by pressing a few keys on the HP-54’s own keyboard. No other equipment is needed. Then start the program

running. In seconds, the HP-65 uses computer technology to solve your problem, with up to 10-digit accuracy. And you can even program it to skip steps or to select alternate steps --- automatically --- if intermediate solutions dictate such action! It couldn’t be easier… or faster!

Actually, the HP-65 is three “answer machines” in one:

  1. It operates on pre-recorded program cards (available from Hewlett-Packard)...
  2. It operates on cards you program yourself (and you don’t have to learn ”computer language”)...
  3. It’s also an advanced scientific pocket calculator (with numerous built-in functions that may be incorporated into a program or used independently).

Whichever way you use the HP-65, you’ll be amazed at how much time and effort it saves you, and how it helps to reduce computational errors.

Equally important, it enables you to handle complex, lengthy or repetitive problems that would be inconvenient, difficult or time-consuming to handle without using devices many times larger, much more expensive and nowhere near as portable as your personal “computer.”

Because it operates on rechargeable batteries as well as on AC, the HP-65 can be used literally anywhere --- at a meeting, out in the field, up in a plane, down in minute you need them --- not hours or days later.

What makes the HP-65 even more incredible is that it’s easy to operate! It can be used even by persons who know absolutely nothing about computers (or about calculators, for that matter). The illustrated Owner’s Handbook clearly explains every detail, and the Quick Reference Guide offers a how-to-do-it summery.

Briefly, here are the three ways you can use it:

1. Use it with pre-recorded program cards...

You don’t need a scientific or engineering background to benefit from the HP-65’s capabilities. But let’s assume, for the moment, that you’re involved in some project concerned with the surface area of the human body. Perhaps you’re a working on a suntan lotion.

All you need do is take one of the pre-recorded program cards that come with the HP-65 --- the card labeled “Body Surface Area (Boyd)” --- and feed it through a slot on one side of your personal “computer.” The information on the card --- the step-by-step sequence of key strokes required to solve the problem --- is duplicated

in the HP-65’s program memory.

Next, using the HP-65’s own keyboard, feed in the height and weight of the particular body you’re measuring.

Now start the program running by pushing a single key on the HP-65.

In less time than it takes to read this sentence, the answer you’re seeking will appear on the HP-65’s light-emitting diode (LED) display!

To calculate the surface area of a different body, just feed in that person’s height and weight… and you get the answer just as quickly.

And in case you are a medical technician, and you also want to find out the cardiac index (the ratio of blood pumped per unit of body surface area), simply key in the cardiac input, and the HP-65 gives you the additional answer.

Dozens of pre-recorded program cards are available…

...and more are on the way. They’re packaged in Application Pacs containing up to 40 cards, and you’ll find complete information on them in the literature accompanying this letter. In addition...

2. You can create your own HP-65 program cards!

No, you don’t have to go to computer programming school --- or hire someone who did. You don’t even have to learn “computer language,” or invest in accessory hardware. All you need to write and record your own program is your HP-65, a pencil, some paper, and one of the blank program cards supplied.

Simply prepare a step-by-step sequence of the HP-65 keys you would press to solve your particular problem. If you wish, this program can include conditional tests, skips or other techniques (all of which are clearly explained in the Owner’s Handbook).

Turn on the HP-65, press the appropriate keys in sequence, and run a blank card through the machine to record the program.

And that’s all you do!

You may use the card again and again, whenever you need it, to cut problem-solving time down to seconds and reduce the possibility of keystroke errors. You can even edit the card, to change or delete any part of the program. Or you can erase the card and record an entirely different program on it.

[If you would rather not work out your own program, you may find exactly what you need among the hundreds of programs --- in a variety of fields --- in the HP-65 Users’Library. See the literature enclosed.]

by creating your own program cards, or by adapting an existing program to your

own specific needs, you greatly extend the versatility of the HP-65 while --- at the same time --- you transform it into a highly specialized, truly personal “computer.”

3. And you can also use the HP-65 as an advanced scientific pocket calculator!

Already pre-programmed into the HP-65 are the most commonly used scientific functions. Included are log and trig functions, the constant for s, the conversion of decimal angles to degrees/minutes/seconds, the conversion of rectangular coordinates to polar coordinates (oe vice versa), and numerous other functions as shown in the enclosed brochure. These built-in functions may be used independently, or incorporated into any program.

So there you have it--- the totally unique three-in-one, pocket-sized personal “computer” – with the “super power” you need to solve just about any problem… anywhere… anytime!

After you read the enclosed literature, you may agree with us that the HP-65 is pretty fantastic. But only a personal trial can prove how valuable --- how indispensable --- it can be to you.

That’s why I invite you to try it for 15 days!

See how it can save you hours --- or perhaps days --- of valuable time and effort, by quickly, easily and accurately solving hundreds of your complex, lengthy or repetitive problems. And see how it can free you from devices that are many times larger, much more expensive and nowhere near as portable as your personal “computer.”

You might expect to pay $2,000 or more for an answer machine as incredible as the HP-65… but it’s only $795.00 (U.S.A. only), complete with accessories as shown in the literature. And if you’re not absolutely fascinated with owning and using your own pocket-sized personal “computer,” return the HP-65 15 days for a full refund or credit!

With a product this unique, it’s possible we may not be able to keep up with initial demand. Therefore, if you are interested in the HP-65, I strongly suggest you take advantage of this 15-day trial offer now.

Cordially,

Advanced Products Division
Hewlett-Packard Company

P.S.

If you send for your HP-65 now, you’ll receive --- at no extra cost --- a year’s subscription to the Users’ Library Catalog of Contributed Programs, to greatly extend the usefulness of this personal “computer.” Please see the enclosed literature for details.
