CHAPTER 1

INTRODUCTION

ABOUT NICE, THE Z80+ EMULATOR

The

NICE Z80+ begins a new

generation

of

medium-to-high

function

emulators.

Its

revolutionary

compact

design

provides

the

following

benefits:

o

Reduction

in

Price.

NICE's low

price

finally brings

In-circuit

emulators

out

of

the

exclusive

domain

of

large-scale

operations

and

into

the

reach

of

computer

repair

shops

and

hobbyists.

o

Transportability.

NICE is only

3i"

X .5f"

and

l"

thick.

Not

only

can

it

be

used

in

development

labs,

it

can

also

be

a

part

of

the

computer

technician's

portable

repair

kit.

An RS232

compatible

interface

allows

NICE

to

hook up

to

most

terminals

and

modems

for

speedy

diagnoses.

o

Full

Speed

Emulation

with

Minimal

Target

Disturbance.

NICE's

compact

design

means

the

electronics

are

closer

to

the

target

system

than

emulators.

The

result

is full

speed

emulation

with minimal

target

disturbance.

The

NICE Z80+

includes

a Molex

connector

to

tap

into

an

external

power

supply

with

a

requirement

of

approximately

IA@

.5.2V.

o Ease

of

Operation.

NICE's

streamlined

operation

is

consistent

with

its

streamlined

design. All

it

takes

to

get

started

is

replacing

the

Z80

microprocessor

with

NICE

(either

directly

or

via

the

40-pin

cable

assem-

bly),

connecting

the

terminal

to

NICE,

resetting

the

target

system,

and

hitting

a

carriage

return.

I.

WHO USES

IT?

NICE is

designed

to

meet

the

needs

of

four

groups:

o

Designers

profit

from

NICE's

ability

to

aid

in debugging

both

hardware

and

software.

Emulators

provide

a

cost-effective

means

of

integrating

hatrd-

ware

and

software.

o

New

Product

Manufacturers

can

use

NICE

to

pinpoint

potential

problems

before

beta

testing.

During

the

manufacturing,

NICE

can

be

used

to

bring

up

virgin

CPU

cards,

then

to

download

and

run

diagnostics.

A

more

trouble-free

product

leads

to

greater

customer

satisfaction.

o

Computer

Repair

Technicians

can

bring

NICE along on

on-site

repair

ca.lls,

possibly

eliminating

the

need

for

in-shop

repair.

Smaller

computer

repair

shops

can

finally

afford

an

emulator

because

of

NICE's low

cost.

o

Serious

hobbyists

can

even

use

NICE.

Its

low

cost

and

high

versatility

combine

to

make

it

a

valuable

tool

for

debugging

home

systems

and

designing

custom

hardware

or

software.

BASIC FEATURES

Despite

its

small

size,

NICE

incorporates

most

of

the

features

of

the

less

portable

and

more

expensive

emulators.

o

Full

speed

execution

up

to

8MHZ

o

Refresh

maintained

at

all

times

o All

1/0

ports

available

to

user

o All

available

to

user

o

Three
