Introduction

Hand Held Products'

71 Memory Modules

(M/M's)

are

a very

powerfulenhancement

for the

Hewlett-Packard

HP-7I computer.

The

71

M/M's are available rn the

following

configurations:

.

Random Access

Memory

(RAM)expansion.

Hand

Held Products

provides

your

choice

of 32K,64K, or

96 Kbyte RAM expansion.

.

Erasable

Programmable Read-Only Memory

(EPROM)

expansion. The EPROM carrier versions

of the

71 M/M's allow

you

to

address up to

32

Kbytes of software in EPROM.

.

RAM/EPROM expansion. The

32KRAM132K

EPROM version

of

the

M/M's

provides

32K

of RAM

as

wellas up to 32Kof EPROM.

As

you

can see, the addition of Hand Held

Products' 71 Memory Modules dramatically increases the memory

of

your

HP-7I computer. Installation

of any of

the77

M/M's

transforms the

HP-71 into a

powerhouse

and can open up a new world

of opportunity

for

HP-71

users.

Tlne

7I

M/M's

are enclósed in the

card-reader

port

of

the

HP-71. The installation

is very

simple. No tools

are

necessary:

1) Türn

off the HP-7I.

2) Türn the

HP-71 over

and remove the

cover

to

the

card-reader

port.

3) Remove the

plastic

insert.

5) Turn

the

HP-71right-side-up and make

certain

the

nameplate

of

the

M/M is flush

with

the

front

of the

HP 77.

6)

Replace the

cover to the

card-reader

port.

Note:

¡

As with

any

plug-in

module,

there is

a chance

of

memory

loss in the

HP-71

when installing

a

71

M/M.

Hand

Held Products

has incorporated

several

features

within theTI

M/M's to minimize

this

occurrence,

however

memory

loss may

still

occur

upon initialinstallation.

We recommend

back-up

of

allfiles

before removing

or installing

any module.

.

Be

careful

not to

press

any keys

on the

HP-71 when

installing

aTIMlM.

.

Make

certain the77

M/M is

seated firmly

in

position

before

turning

on the

HP

71.

o

Do not

force

the

TIMIM into

the

port.

The

TIMIM

willfit

snugly

but the

sockets

on

the

71 M/M must

be

properly

aligned

with the

pins

To

remove aTIMlM

from the HP-7I:

1) Turn off

the HP-71.

2) Remove

the door to the card-reader

port.

3) Using

your

thumbs,

press

downward on

the

embossed

side

(top)of

the

while

guiding

the Module out with

your

fingers. Use even

and be sure the M/M

is

pushed

as

possible.

. RAM

Hand

Held Products'

71

Memory

Modules'offer

you

the flexibility of using

your

extended

memory

in two

ways:

.

Main Memory When a 71

RAM M/M is

installed,

you

have

instantly

added 32K,64K, or 96Kbytes

of RAM

to

your

HP-

71.

This

additional

memory becomes a

part

of Main

RAM in

your

HP-71. A simple

MEM test willshow

the additional

RAM in the HP-71. Type MEM

fÑDTiÑElto

show

the increased memory on

the

HP-77 display.

.

lndependent Memory

Your increased

memory can also

be

partitioned

or

placed

in

independent RAM. The

additionalmemory

'

resides in

port

5 of

the HP-7I. The 32K

RAM, 64K

RAM, and 96K RAM

M/M's can be

partitioned

in

32K

increments and are addressed

in the following

locations:

32K....."..port

5.0

64K... . ..port 5.0 and

5.01

96K... . . .ports 5.0,

5.01, and 5.02

To show

the amount of additional

RAM when

partitioned,

type SHOWPORT

IEÑDIINB.

Execution of

the

SHOWPORT

command will

display the

port

number where

the

additional

memory resides, memory capacity

in bytes, and a

memory type of

"1"

indicating independent RAM.

Note:

Other

independent memory configurations

in

increments of

32K

are available. Consult

Hand Held

Products for

further information.

T]¡..e 32K

M/M to

T\e

77

M/M's battery

is in

operation

only when the

module

is removed from the HP-71i.e. there

is no

drain

on the M/M's battery while

installed in the HP-71.

When

installed in the HP-71, all 71 M/M's are

powered

by the HP-71's

power

source. The snap-on

cover which

is

provided

with

your

7lMlM

is

extremely

important

with

regard to the battery

life

of

your

32K

RAM and

64K

RAM Memory Module. The cover should

be

placed

on

the

M/M

immediately upon the removal

of

the module from the HP-71and must remain

on

the module

at all

times when not installed

in

the HP-71.

¡

Battery Life Your 64K battery

backed-up M/M should retain its

memory

for approximately

13 months while

your

32K battery backed-up

M/M willretain it's memory

for

approximately 29 months.

These

figures

are

based

upon

"worst-case"

conditions.

That

condition

would have the

M/M

"sitting

on

the

shelf'with the

cover intact

and

never

being installed in the HP-71.

Under

normal

use

i.e.

being installed in the

HP-71far

more

frequently,

your

battery backed-up

M/M will

retain its

memory ever longer.

Once again, to

maximize

the life of the

battery,

the

snap-on

cover must

be on the M/M

any

time

the

Module is

outside the

HP-71.

Note: "Normal

use"

is

considered as leaving the

M/M inside

the HP-71

approximately 80o/o

of

the time.

Under this

condition

your

battery life should

extend up to 5

years.

It

is

a simple task to replace

the battery in

your

M/M.

The only material

necessary is

a 71 M/M

Battery Replacement

Assembly which

comes complete

with everything

you

need

and can be installed in

minutes.

. . . EPROM

Carrier

Versions

TheTl

M/M's

offer two

options

for

adding

EPROM to

the HP-71:

the

EPROM

carrier

by itself

or the

EPROM

carrier

with

32K

of RAM.

The EPROM

functions

the

both

versions.

Opening the

case

The7l

M/M's

are

enclosed in

plastic

cases

which

have

been

designed

to

allow

easy access inside

the

Modules.

Hand

Held Products

has

utilized

a

specially-designed

adhesive

tape

which

acts as

a

hinge for

the

case.

Do not

remove

the tape-the

case

opens

at the

opposite

end. To

open the

case:

1)

Grasp

the

case as indicated

in

the

photograph.

2) Apply

pressure

with

your

thumb

on

the lower

half

of

the

case

while

gently pulling

upward

on

the top

half

of

the

case.

3) The

case should now

be open.

o

Installing the EPROM

You may install

up

to

32K of EPROM in

your

71

M/M

EPROM

Carrier.

The following EPROM may

be

used:

Intel"

compatible,

CMOS,

27256,

27 I28, 27 64, 200 nanosecond

or

faster.

To install

a32K EPROM, the'jumper"

should

remain

on the

pins

marked

A and B in the

photo-

graph.

To installa 16K

or smaller EPROM, simply lift

the

jumper

off of the

pins

marked

A and B and

place

the

jumper

over

the

pins

marked B and

C.

Jumper

5) Turn

the

HP-71right-side-up and make nameplate HP 77.

6)

Replace the

Jumpeq

position

for

8K

or l6K EPROM

With the

jumper

in the correct

place,

the EPROM

may be installed in the socket of the

Carrier.

The

locator mark

(pin

1)

of

the EPROM

should be

oriented

to the

left or'jumper side" of the

Carrier.

With

the

EPROM seated in

place,

close the case and

installthe M/M

in

the HP-71.

o

Addressing

the memory

In the

EPROM

Carrier

version

of the

71 M/M. the

EPROM

is

addressed

in

port

5.0. In the

32K

RAM/32K

EPROM

M/M the

EPROM

is

addressed

in

port

5.0

and the

RAM

is in

port

5.01.

o

Note: The

EPROM

Carrier

always

occupies

32K of

memory

space,

regardless

of the

size

EPROM

actually

used.

.

The

snap-on

cover

which

comes

with

your

TIMIM

should

remain

on

allthe

Modules

when

they

are not

installed

in the

HP-71.

The

cover

protects

your

Memory

Module

against

electrostatic

discharge

as

well

as

extends

the

battery

life

of

the

32K and

64K

RAM

M/M's.
