HP-65

Congratulations

purchasing

your

HP-65

Programmable

Pocket

Calculator.

In addition

all

the

computational

capa-

bilities

that

have

made

the

earlier

HP-35

and

HP-45

models

popular

with

professional

people,

your

new

HP-65

offers

fea-

ture

that

other

pocket

calculator

can

provide:

true

program-

mability.

Simply

defined,

programmability

HP-65’s

ability

and

The

value

this

feature

becomes

clearer

when

consider

that

most

who

routinely

work

with

numbers

spend

great

deal

time

doing

the

same

types

of calculations

over

and

over

again.

matter

whether

we're

preparing

flight

plans,

surveying

construction

sites,

calculating

returns-on-investment,

designing

power

supplies,

can

all

identify

repetitive,

time-consuming

problems

which

diminish

our

productivity

and

frustrate

our

goals.

Although

programmable

computers

and

desk-top

calculators

have been

available

for

some

time,

their

expense,

complexity

and

non-portability

have

made

them

inappropriate

impractical

for

many

tasks.

The

real

significance

the

HP-65

that

overcomes

these

limitations

and

lets

almost

anyone

enjoy

the

advantages

—speed,

accuracy,

convenience

—of

programmable

device.

You

can

use

this

powerful

device

three

ways:

Calculate

Manually

You

you

enter

etc.,

you

can

with

minimal

effort

the calcu-

lator

itself.

You

load

card

into

the

calculator

and

let

the

stored

program

handle

the

busy

part

the

calculation.

Typically,

you

just

key

the

data

and

start

the

program

running.
