jointly

announced

a

cooperation

in

the

field

of

micro-

The

agreement

covers

a

cooperation

for

both

current

It

provides

the

means

to

establish

alternate

sourcing

of

each

other's

microcomputer

Both

companies

reported

that

they

felt

the

agreement

would

accelerate

their

development

and

promote

the

use

of

this

new

technology.

ROCKWELL

PPS-8

Ass

EMULATOR

Rockwell

Int'l

has

announced

off-the-shelf

availability

of

a new

"Assemulator"

which

it

described

as

a

"total

system

development

tool"

for

its

8-bit

PPS

micr090mputers.

The new

instrument

facilitates

assembly,

debugging

and

modification

of

programs

while

enabling

real-time

software

check-out

of

systems

with

peripherals,

encoding

of

PROMs

and

EROMs

for

field

testing

of

prototypes,

the

generation

of

ROM

codes,

and

can

even

be

used

for

acceptance

testing

of

Rockwell's

devices

and

boards.

Complete

with

software

and

comprehensive

programming

and

operating

manuals,

the

instru-

ment,

which

is

designated

the

PPS-8MP,

sells

for

$3,450.

The PPS-8MP

AGREEMENT

(from

Last

month,

suit

was

brought

in

New

York

against

Fairchild

and

Dr.

David

Chung

by

Gen-

eral

Instrument

Corp.

claiming

Fairchild

had

acquired

information

about

Olympia's

micro-

processor

system

from Dr. Chung, a

former

Gen-

eral

Instrument

employee.

The

complaint

al-

leged

this

information

was

used

in

the

design

of

the

F-S-microprocessor.

Fairchild,

which

had

denied

the

allegations,

said

the

Olympia-Fairchild

agreement

includes

a

complete

release

for

any

possible

use

of

Olympia's

information

in

the

microproces-_

sor

otherwise.

or,

if

desired,

the

The

SX

200

is

a

low-end

device

intended

principally

for

applications

in

the

home

industry.

The

microprocessor

is

com-

with

touch-plate

controls

and

can

be

synchronized

with

the

AC

power

line

for

direct

control

of

such

power

devices

as

SCRs.

A

second

4-bit

microprocessor,

Bitsy,

is

similar

to

the

SX

200

but

lacks

its

touch-

plate

compatibility

and

power-line

synchroni-

zation.

A

PROM

programmable

hardware

emulator

is

available-and

software

support

includes

Van

emphasized

that

this

Development

Sys-

tem

by

Processor

Applications

Ltd.,

is

the

latest

software

development

tool

designed

for

the

Signetics

2650

microproce~sor.

According

to

Dan

Nesin,

president,

the

hardware

design

has

been

optimized

to

provide

maximu~

versa-

tility

and

reliability

to

the

user

at

minimum

cost.

At

the

system's

heart

is

a

Signetics

2650

microprocessor

which

resides

on

the

CPU

card

together

with

the

~Pal

Monpal

system

monitor.

The

monitor

is

contained

in

2K

bytes

of

PROM.

An

I/O

interface

card

contains

all

the

neces-

sary

logic

to

interface

the

265

a

TTY,

CRT

or

a

high

speed

paper

tape

reader.

An

interface

is

provided

as

well

as

a

con-

trol

line

for

an

external

device

such

as

an

ASR-33

reader.

The

8K

memory

card,

which

completes

the

basic

system,

is

fabricated

with

popular

stat-

ic

RAMs

and

can

be

strapped

to

reside

anywhere

in

the

2750

usable

memory

space.

Nesin

said

the

~Pal

Fixit

editor

is

a

char-

acter

string

editor

available

standard

on

paper

tape

or

purchasable

in

PROM.

The

resi-

dent

version

does

not

have

to

be

loaded

for

each

use.

The

~Pal

assembler

is

contained

in

5K

bytes

of

memory.

Variable

length

symbolS

are

used

to

optimize

space

with

the

assembler

support-

ing

approximately

380

4-character

labels

in

the

basic

system.

The

assembler

also

allows

(1)

the

symbols

to

be

defined

externally

and

(2)

large

pro-

grams

to

be

segmented

on

tape

for

ease

of

storage

and

future

editing.

Left

is

provided

to

which

is

to

allow

the

incorporates

both

a

AMD

INTRODUCES

4K

RAMs

Advanced

Micro

Devices

has

announced

a new

pair

of

4K

dynamic

RAMs.

Available

in

a

22-

pin

package

with

separate

data

input/output

circuitry

or

in

an

18-pin

version

with

common

data

I/O

circuitry.

AMD

says

the

devices

were

developed

as

superior

plug-in

replace-

ments

for

similar

parts

manufactured

by

Intel

and

·TI

as

well

as

others.

Designated

the

AM9050

(18-pin)

and

AM9060

(22-pin),

these

silicon

gate

MaS

memories

feature

access

times

to

200

ns

and

maximum

power

dissipation

of

750

mW.

Both

devices

require

only

a

single

clock

and

all

inputs

and

outputs

except

clock

are

TTL

compatible.

The

RAMs

are

available

for

immediate

de-

livery

from

Hamilton/Avnet,

Cramer

and

Schwe~

ber

Electronics.

Prices

in

100-up

quantities

begin

at

$15.30.

MOS

EQUIVALENTS

OF

BIPOLAR

lK

RAMs

The

first

MOS

equivalents

of

1024-bit

bi-

polar

high-speed

RAMs

have

been

introduced

by

Intel

Corp.

The new

Intel

2115

and

2125

fam-

ily

can

operate

as

fast

as

their

bipolar

count~rpa~ts,

at

the

same power

supply

vol-

tage

(+5V)

and

logic

levels.

However,

they

cost

less

and

reduce

memory

system

power

dis-

sipation

by

35%

or

more.

. The

In:el

2115

and

2125

are

TTL

compatible,

pln-for-pln

replacements

of

the

93415

and

93425

lK

bipolar

RAMs.

Both

are

fully

de-

coded,

l6-pin

designs.

The 2115

has

open-col-

lector

outputs

while

the

2125

has

three-state

outputs.

The

fami~y

was

introduced

in

two

speed

grades

and

a

low

power

version.

The

-2

devices

have

a

maximum

access

time

of

70

ns

while

the

non-dash

memories

have

access

time

of

95

ns.

The

2ll5L

and

2l25L

have

a

maximum

current

of

65

with

an

access

time

of

95

GILAUNCHES

SUIT

AGAINST

FAIRCHILD

Citing

that

Fairchild

developed

its

F-8

microprocessor

technology

from

confidential

information

obtained

from

a

former

employee,

General

Instrument

Corp.

filed

suit

against

Fairchild

Camera &

Instrument

Corp.

last

month.

The

suit

seeks

a

permanent

injunction

against

Fairchild's

production

and

sale

of

the

F-8

microprocessor,

as

well

as

compensa-

tory

and

punitive

complaint,

GI

claims

that

in

Fairchild

hired

David Chung,

former

GI

manager

of

microprocessor

development

programs,

who

at

that

time

was

working

on

an

8-bit

micro-

processor

system

that

G1

alleges

~as

the

source

of
