HP's interest in computation evolved as a na turalextension of our traditional involvement in measurement problem solving. At an early date. HP recognizedthe growing need for a family of computationalproducts uniquely designed for ease of interface withscientific instrumentation.In 1966 we in troduced the first d igital minicomputerspecifically designed 10 meet th is need. Soon after, wefollowed up with our f irSt programmable calcula tor .From these modest beginning

FOREWO RDTo g , ~ e you more computing power, your HP 35 works ina consistent and natural way that may be slightlv different from p r e ~ i o u s calculators you have operated. So evenif you are an eNd hand at using calcuiatOfs, you will find itworthwhile to read this little book. Beginners, too. willfind the step bV step explanation easy to follow.

SHIRT POCKET POWER

Our object in developing the Hp35 was to gIve you a hi(flpreciSIon portable electronic slide rule. We t h o u ~ " " I I you'dlike to have something only ficllonal heroes like JamesBond, Walter MitIY or D,ck Tracy are supposed to own.The HP35 has far more computing power than previouspocket calculators. Its ten digit accuracy exceeds theprecIsion to which most of the phYsical connants of theuniverse are known. It wil l handle numbers as small as10-99 and up to 1099 . Jnd automa t ica lly places thedecimal point for you . It is th e first pocket calculato r toprovide YOU with tran:;.cendenta l functions like logarithmsand sines and cosines. The operational $lack and thereverse "Polish' (Lukasiewicz) notation used in the HP.35are the most efficient way known to computer :;.cience forevaluating m!lIhematical expressions.

The HP35 was designed with yOU, the user, In mind. Wespent as much time on the keyboa rd layout. on the chOiceof functions, and on the styling as we did on theelectronics.

The speed and convenience with which you can arrive at aSolution to a problem is unparalleled. Vou will find thatfewer mistakes occur when compu tations are easier tomake. You will also find yoursei f performing calculationsyou did nOt do bef ore. They fa ll into Three categor ies:firsT, Those calculations in your own field that wereavoided in favor ot an educated guess. The ability toperlorm complex calculations whereV(! r you are and what ever me situation will enhance your prolessional staTure.The second category consists of calculations indirectlyrelated to your pro fe ssion - computing the return on aninveslment, reconciling your bank account, pursuing yourhobby with professional precision, etc. The last categOfYcontains thO$!! expioratOfY calculations that you do forlun. They arise when someone asks "Old youknow . . . ?". For example, did you know th ai one cubicmile of air weighs more than 5 million tons?Did you know that a man running a 4--minute mile turns100 yards in a little more man 13.6 seconds?Did you know that 355 / 113 is an excellent approxi mation to n?

Why not check and see just how close 356/ 11 3 doesapproximate 11? Although the rest 01 this manua l must beread , JUSt between the IWO of us, you can't hurt Ihecalculator by sliding the power switch to ON and pressinga lew keys,To check the approxima t ion, key in 355, then pressIDJiiIl and key in the denominator, 113, N

THE OPERATIONAL STACKTo do the last examples your HP-35 had to save someanswers for future use. Let's see how it does this. Thereare four number registers in the HP-35, which we call theX, Y, Z and T regIsters. They are arranged in what iscalled a "stock", X on the bottom and T on the top. Thedisplay always shows the number in the X register.OPERATIONAL STACK

,yx

___ T Regis ter___ Z Register___ Y RegIs ter

X Register

NOTEThe x Register is~ I w ~ y ~ r l i ~ n l ~ Y f l r l

To avoid confusion between the name of aregister and the numberin it, we designate theregister by a capitallener and the numberby italics. Thus, X, y, Zand I are the contentsn / X , Y , 7 ~ " d T

When you key in 11 number, it goos into the X register,Which is the only one displayed. When you pressIlDEiD ,this number is repeated into the Y regis te r. Atthe same time, the y is moved up to Z arxl z is moved upto T like this:

When you press a ,Xisadded toy, and the whole stackdrops to d,splay the answer In X. The same Ihinghappeosfor= I and G Whenell(!r the stack drops, I isduplicated into T and Z, and Z drops 10 Y.
