THIS

MANUAL

This manual may

be

used in two ways;

1. as a textbook

from

which

to

learn how to use and program

your

calculator, and

2. as a

'quick

-reference',

to

determine what a

particular

key

or

svvitch will do and the purpese

for

which

it

may be used.

As

a textbook,

the

manual progresses in a learn1ng sequence

which presupposes no previous experience with

this

type

of

calculator

or

with

programming.

For 'quick-reference' the key index on Page iv is used

to

locate

the

required key

or

switch in

the

text. Each key is

briefly

described in bald

print.

This is followed by a more detailed ex-

planation with examples which

illustrate

what

the

key does and

the purposes

for

which

it

may

be

used.

FROM

9100A

TO

91008

I I

For the benefit of

91008

users who have previously used and

programmed only

the

9100A

Calculator, here is a

briet

sum-

mary

of

the

91008

features and characteristics which

differ

from

those

of

the 91

OOA.

1. The

91008

has a Iarger programmable memory which is

divided into two pages,

the

( + ) page and

the

(- ) page

(see Pages 8 and

57)

.

The (

-t

) page consists of

16

registers designated (

-t

) 0

through

(+ ) f ; these are identical to

the

0

through

f

registers

of

the 91

OOA.

The ( ) page consists

of

16

similar

registers, (- ) 0

through

( ) f .

The sign of

the

page (-:-

or

- ) is required

for

addressing

the

memory and

for

branching between pages;

the

sign

is not required

if

the branch is to

an

address

on

the

same

page

as

the branch

instruction

(see 'GO TO' key on Page

68

).

PREFACE

2. The

91008

has

subroutine

capability

which is

controlled

by

the

'SUB/RETURN' instruct1on (see Pages

60

and

94

).

3.

An

extra recall

instruction.

'to

x

from'

(x~t

J), is available

to

recall data

from

the

( , )

numeric

and ( )

alphameric

registers (see Page

38

).

4. ln

the

'RUN'

mode, 'STEP PRGM' no Ionger causes an

im·

mediate

branch

except when a

'not

met'

'I

F'

qua

Iiter

1s

encountered (see 'EDITING A PROGRAM' on Page

76

).

ln the 'PROGRAM' mode, as 'STEP PRGM' is pressed,

the

X register displays

the

address and operation (as before)

and

the

Z

register

displays

the

operation.

5. Conditional

branching

remains as in the

9100A

except

that

the

plus

(+ ) and

minus

( ) signs

cannot

follow

an

'I

F'

instruction

unless they are

pa

rt

of

an address.

'CONT(inue)'

cannot

be used as a 'no

operation

'

after

an

'IF'

instruction

if

'CONT' is

tobe

followed by an

alphameric

or

sign (

-t

or

)

instruction.

6. When

storing

or

recalling

data,

the

sign

of

the

page

ts

al-

ways required

if

the

storage

register

is on

the

( ) page;

the

sign

of

the page is never

required

lf

the

storage regts-

ter

is on

the

( t ) page. Thts is

true

regardless

of

whtch

page

contains

the

'store'

or

'recall'

instructions.

7. Operation

of

the

'ACC

~

·,

'ACC ' and 'RCL' keys is exactly

as

1n

the

9100A

in

that

only the (

)e

and ( ) f

register

s

are affected.

'CLEAR' clears

the

( ) e . ( )f ,

X.

Y and Z registers

and

the

'ARC' and 'HYPER'

conditions,

as

tn

the

9100A

.

8.

'END'

is

no

t a required last ins

tructton

in a

program

whtch

is

to

be recorded on a

magnetic

card (see 'END' on Page

70

GENERAL

INFORMATIO

This section contains general

information

about the Model

91008,

its accessones, servicing

information,

etc. Also in·

cluded is the turn-on procedure and a method

for

checking

the performance

of

your calculator.

Your Hewlett-Packard

91008

Calculator is

an

easy-to-use,

yet

scientific, desk-top calculator.

lt

is capable

of

performing

operations ranging

from

the very

simple

to

the very complex,

such

as

are encountered in business, educational,

scientific

and engineering problems. Trigonometrie,

logarithmic

and

mathematical functions are performed

with

single key strokes.

The

91008

is also programmable: its computer-like

memory

enables the calculator

to

store

instructions

and data

for

repet1·

tive and iterative solutions. Conditional

branching

(which allows

the calculator

to

automatically make decisions while

performing

a program) and the use

of

subroutines provides complete pro-

gramming

capability. Knowledge

of

special 'machine language'

is

not

required in

order

to

program

your

calculator.

Programs can be recorded on the magnetic cards supplied

with

the calculator. Recorded programs can be reinserted into

the

calculator at a later date,

thu

s

eliminating

repetition

of

the

time-consuming step-by-step entry. A

pull-out

instruction

card

is located, at the

front

of

your

calculator, below the keyboard;

the operation of each key is

briefly

explained on

this

card.

KNOW

YOUR

91008

This section contains general information about the Model

91008,

which you will need in order

to

operate the calculator

effectively. Terms are explained, wherever they

first

appear.

The examples given in this section are not intended

to

teach

the keyboard, but

to

illustrate the points

be1ng

made in the

text;

by

performing the examples, however, you will develop

a 'feel'

for

your calculator.

Your

91008

is an extremely powerful instrument with a wide

range

of

capabilities.

lt

may

be

efficie'ntly used

to

perform cal-

culations ranging from the simple adding-machine type

of

cal-

culation up

to

highly sophisticated sc1entific computations. The

calculator is particularly valuable in solving problems which are

complex but which involve only a moderate amount

of

data,

the type of calculation which previously required a computer;

in this respect, because

of

the wide range of numbers which can

be

handled at any one

time

(from 1 x

10

-98

to

9.

999

999 999

x

109

9

),

the

91008

Calculator

can

outperform many computer

s.

Despite its tremendous capability the calculator remains simple

to

operate.

The

91008

uses two memory systems. One is a unique Hewlett-

Packard

Read

-Only -Memory (ROM). The

ROM

contains all

the routines ('wired-in' programs) necessary

to

execute the

instructions and calculate the many functions which can

be

call-

ed

from the keyboard. These routines are fixed and cannot

be

changed in any way by the person operating the calculator.

The second memory is a magnetic-core memory;

this

adds

to

the calculator the capability

of

storing data and

of

being pro-

grammed to automatically process

that

data.

This

memory

consists

of

35

'registers'.

Nineteen

of

the regis-

ters

are

shown in

the

diagrammatic

sketch

of

Figure

1;

the

registers

are

the

horizontal

rows

designated

(

+)

0

through

(+ ) F

and

x,

y

and

z.

The

sixteen registers,

(-1

-) 0

through

(+ )

F,

form

a

'page',

the

'(+)

page'; a

further

sixteen regis-

ters

(not

shown in Figure 1)

designated

(- ) 0

through

(- ) F

form

a

similar

page,

the

'(

- ) page'. The

total

of

thirty-two

registers

on

the

(+ )

and

(- ) pages is used

for

storing

either

program

steps

or

data

(as shown in Figure 1). The

three

re-

maining

registers, (x, y

and

z)

contain

the

information

which

is

displayed

on

the

calculator

screen.

On each

of

the

two

pages,

the

first

14

registers

, (

+)

0

through

(+ )

d,

can be used

for

storing

either

program

steps

or

data;

each

register

contains

14

'characters',

these

are

the

horizontal

locations

designated

0

through

d

(the

+

or

-sign is

not

re-

quired

for

the

characters).

Each

character

can

contain

either

one

program

step

(one key pressed)

or

one

digit

of

a data

number;

if

no data is

stored

in

the

(+ ) 0

through

(+)d

registers

then

a

maximum

of

392

(2 x

14

x

14)

program

steps

can b .a.ecommodated.

Program steps and data cannot both

be

stored in any one regis-

ter

at the same time. Each data number requires a complete

register

(14

characters)

for

storage, thus

for

each data number

stored the maximum possible number

of

program steps is re-

duced by 14.

The remaining two registers (

+)

e and (

+)

F , on each page,

are used

for

data storage only.
