not

replace

User’s

came

with

the

Rather,

itis

book,

“a

guide.”

The

User’s

Guide

documents

each

but

not

About

Your

Palmtop

What

Cannot

The

Palmtop

real

PC—roughly

equivalent

IBM

with

mono-

chrome

display

and

MS-DOS

version

3.22.

And

just

any

such

PC,

itis

limited

the software

available

for

it.

Some

programs

for

desktop

XT-compatible

will

not

work

the

Palmtop—especially

they

need

graphic

display

extended

memory

(see

pages

111

and

123).

What

Can

Do—If

You

Really

Insist

The

Palmtop

not

really

designed

write

books,

publish

elaborate

spreadsheets,

develop

software,

etc.

You

can

those

things,

but

you’d

working

harder

than

necessary;

far

better

use

desktop

for

such

tasks.

For

example,

the

Palmtop

has a

Memo

Editor

with

some

standard

word-processing

features,

but

its

keyboard

size

not

the

best

for

touch-typing

lengthy

document.

Likewise,

the

built-in

2-3

program

great

for

analyzing,

but

you'll

find

convenient

the

final

presentation

Was

Designed

The

that

the

things

You

Already

Know

About

PC’s

You'll

find

that

many

the

Palmtop’s

features

behave

other

PC’s.

All

the

built-in

have

One

big

difference

between

the

Palmtop

and

other

PC’s

that

you

can

have

multiple

applications

open

simultaneously

the

Palmtop—and

switch

press-

ing

just

one

key

(although

you

can’t

access

unless

all

(more

You

Already

Know

About

Calculators

you've

used

any

HP’s

recent

financial

calculators,

you'll

find

that

the

Palmtop

Calculator

feature

can

just

about

everything

they

can

(though

may

take

you

some

time

adjust

how

those

calculator

features

look

the

Palmtop’s

screen).

The

big

difference

between

the

calculators

and

the

Palmtop

how

the

Palmtop

uses

built-in

Lotus

1-2-3

templates

statistical

and

cash-flow

analyses.

About

Looking

the

Keyboard

The

keyboard

not

the

standard

keyboard,

it’s

probably

convenient.

Take

look:

Character

Keys

The

are

standard

format.

The

gold

shift

key

(©)

and

the

special

character

key

(CHAR)

give

you

access

special

punctuation,

international,

and

symbolic

characters

(summa-

rized

pages

140-142).

These

keys

are

“sticky”

keys:

once

you

press

(<),,

the

key

you

press

will

produce

the

shifted

character.

Unlike

standard

keyboard,

you

don’t

have

hold

down

(&)

while

you

press

other

alphabet

keys.

The

characters

(bottom

are

given

their

own

keys

because

only

when

There

are

several
