User's

Group

Newsletter

October,

1981

From

the

Editors

The

response

has been amazing!

In

one

month more

than

150 membership

applications

have been

received;

more

than

100

disks

from

the

library

have

been

sent

out.

There

actually

are

Terak

users

out

there!

A

warm

"thank

you" must be

extended

to

all

those

persons

who

have

filled

out

membership

applications.

It

shows

that

there

is

a need and

support

for

a

User's

Group

of

this

kind.

Now

if

only

those

persons

who

have been

waiting

for

the

right

moment

will

go ahead and

fill

out

and send

in

the

membership

application,

the

membership

rolls

would

probably

double

in

a month

again.

Please

take

a

couple

of

minutes

to

fill

out

the

application

and

mail

it.

It

is

the

only

method

used

to

generate

a

final

mailing

list

for

the

Newsletter

and

Bulletin.

If

an

application

is

not

on

file,

no

copies

will

be

sent.

You

are

not

automatically

on

the

mailing

list

just

because you

received

a copy

of

the

first

issue.

And

if

your

Newsletter

copies

of

the

and

Bulletin

first

have

disappeared,

write

and

ask

for

more.

Extra

membership forms

will

gladly

be

sent

along

as

well.

More

than

one

person

at

a Terak

installation

site

may

join

-

there

is

no

limit

to

the

number

of

people

that

may

join.

Actually,

the

more

the

merrier.

To

those

diehards

who

have

jOined,

welcome.

And

lets

make

this

group

into

a

tool

that

best

serves

everybody's

interests.

And

from

the

Ed~tor

-Thank

You.

You

have shown

that

this

idea,

at

least,

isn't

just

a

flash

on

the

screen.

As

a

final

note,

we

would

like

to

take

-1-

this

opportunity

to

congratulate

and

thank

the

Terak

Engineering

Group.

This

group

of

people

has

worked

very

diligently

to

get

several

new

Terak

products

into

production

but

get

very

little

public

recognition

for

all

their

hard

work.

So

at

this

time

we

want

to

say:

"Stand

up

and

take

a

bow.

And

THANKS!"

(See

the

product

plugs,

in

"And

Now

a

Word

From

Our

Sponsers".)

About

Software

Requests

There have been

over

50

Software

Requests

ordering

software

from

the

User's

Group

Library.

This

is

great,

as

it

shows

that

the

software

in

the

Library

can be

useful

to

people.

But

in

the

process

of

filling

these

orders

several

points

have

come

to

light:

PLEASE,

please

do

not

send

just

purchase

orders.

The

User's

Group

is

independent

of

the

Terak

Corporation

and has

no

way

of

processing

PO's.

Please

make

the

request

that

a check be

processed

and

included

with

the

purchase

order.

All

purchasing

offices

will

do

this,

especially

for

the

small

amounts

of

money

necessary

to

order

Library

software.

Please

make

sure

that

all

orders

are

sent

to

the

Terak

User's

Group

address.

Currently

this

coincides

with

the

Terak

Corporation

address.

This

can be

confusing

for

Purchasing

Offices.

They have a

tendency

to

include

your

Software

Requests

with

general

purchases

which

are

sent

to

the

Terak

Corporation.

The

Checks

are

then

sent

directly

to

the

bank and

the

software

order

forms

are

never

seen

again.

This

can cause an

unreasonable

delay

as

the

orders

are

chased

down.

Do

make

sure

The

bank

gets

a

bit

suspicious

when.

the

checks

are

deposited.

Long

hours

are

spent

pleading

with

the

teller

to

accept

the

checks and

not

to

worry

(they

probably

still

do).

Do

include

a

return

shipping

address

with

the

order

form.

One

order

is

sitting

waiting

to

be

processed because

the

check has

no

address

on

it

and

the

order

form

is

equally

blank

in

that

a~ea.

All

orders

are

being

shipped

via

UPS.

If

this

causes

a

hardship

(i.e.

the

closest

is

away),

please

indicate

address

that

the

is

to

be shipped

via

On

January

6,

1978,

the

(SUNY,

Albany)

Computing Center submitted a

proposal

to

the

Higher

Educational

Instructional

Equipment Grants Program

for

matching

funds

to

purchase desktop

microcomputers,

believing

that

with

the

advent

of

this

new

technology

the

opportunity

existed

to

radically

change

the

way

students

learn

from and about

computers.

On

June

1,

1978

the

desktop

computer

selection

committee agreed

to

purchase a model 8510/a from

the

Terak

Corporation

as

it

clearly

met

all

the

requirements

of

the

Request For Quote.

As

an

active

member

of

the

selection

committee, Dr.

Ernest

Scat

ton

of

the

-2-

Department

of

Slavic

Languages and

Literatures

was

especially

intrigued

about

this

desktop system because

of

the

new

areas

of

linguistics

that

could be

explored

via

Terak's

programmable

character

set.

For

some

time Dr.

Scatton

had been

searching.

for

a mechanism

by

which

computers could be used

to

aid

in

teaching

foreign

languages

(specifically

Russian).

Upon

learning

that

one Terak

unit

would

arrive

at

Albany

in

the

Fall

of

1978,

Dr.

Scat

ton

decided

to

seek

out

colleagues

at

other

academic

institutions

that·

were

already

using

Terak systems and developing

software

for

them.

In

the

early

winter

of

1978-79, Dr.

Scatton

visited

the

University

of

Minnesota where a group

headed

by

Dr.

Peter

Patton

was

developing

Terak

software

for

a

variety

of

academic

disciplines,

including

the

language

area.

Dr.

Scat

ton

returned

to

Albany

confident

that

software

could

be

designed and implemented on

the

Terak

8510/a

to

assist

in

the

teaching

of

foreign

languages and

character

set

problems, and began

this

work almost immediately. Although

he

insists

that

he

is

not

a "computer

programmer"

or

"technician",

Dr.

Scatton

and

his

assistants

have over

the'

past

year

and a

half

produced a

great

deal

of

applications

software

to

assist

in

the

classroom -

particularly

with

respect

to

teaching

Russian.

Utilities

Support

In

order

to

facilitate

the

proposed

departmental

projects,

a

considerable

amount

of

time

was

devoted

to

the

design

and implementation

of

various

utility

programs and

to

the

modification

of

existing

systems

software.

Much

of

that

work

was

Terak's

ability

to

handle

user-designed

character

sets

(making

it

possible

to

use Russian

Cyrillic

and

English

alphabets

simultaneously)

and

its

graphics

capabilities.

the

help

of

utilities,

instructional

programs were

written

to

assist

in

courses

in

languages

and

linguistics,

both

at

the

undergraduate

and

graduate

levels.

Instructional

Programs

Two

major

instructional

programs were

completed.

The

"Articulatory

Tract"

included

a

series

of

four

tutorials

which were produced making

use

of

a

graphios

display

on

the

Terak

of

the

human

vocal

tract

to

teach

and

finally

test

the

commonly

used

nomenclature

for

the

organs

and

spaces

used

in

human

speech.

Russian

phonetics

was

the

second major

instructional

effort.

A program was

designed

to

simulate

Russian

phonetic

transcription

and

to

teach

the

linguistic

rules

which

it

involves.

The

program

accepts

a

Russian

word

in

standard

Cyrillic

orthography

and

illustrates

the

generation

of

its

transcription

by

the

step-by-step

application

of

major

phonetic

rules.

The

program makes

considerable

use

of

graphics

to

provide

the

user

with

screen

displays

explaining

actions

taken

by

the

program. These

displays

replicate

handouts

provided

to

the

student.

Research

in

Russian

literary

bibliographies

concentrated

on

the

design

and implemention

of

a system

to

facilitate

creation

of

bibl~ographic

data

files

containing

both

Latin

and

Cyrillic

material.

Taking

advantage

of

the

Terak's

character

handling

ability,

a

character

set

containing

both

full

upper

and lower

case

English

and

Russian

alphabets

was

built.

The

original

aim

of

the

project

was

to

make

it

possible

to

·compute"

in

Russian

as

well

as

English.

As

a

practical

application,

it

is

presently

being

used

to

build

computer-based

literary

bibliographies

made

available

in

machine

readable

form

or

as

camera-ready

copy. Using

this

-3-

system,

a complete

bibliography

of

the

important

Russian

literary

journal,

Vestnik

Literatury,

has been

entered.

ng

With

the

acquisition

of

a

Cyrillic

font

for

the

Computing

Center's

Compugraphic

typesetter,the

Slavic

Languages

Department

uses

the

Terak

to

input

and

prepare

Cyrillic

material

for

typesetting.

Both

the

Cyrillic

and

Roman

alphabets

can be viewed

Simultaneously

on

the

screen.

This

makes

transliteration

schemes

unnecessary.

The

software

was

recently

used

to

input,

edit,

and

typeset

two

mixed

Russian-English

texts.

The

first

was a

certificate

of

participation

awarded

to

high

school

students

who

took

part

in

a

Russian

language

competition

sponsered

by

the

Slavic

Languages

Department;

the

second was a

Russian

text

with

accompanying

notes

and

glossary,

suitable

for

inclusion

in

a

Russian

reader

or

for

use

in

an advanced

course

in

reading

and

translating

Russian.

The

hope

is

to

be

able

to

obtain

high-quality

camera-ready

copy

of

Cyrillic

material

at

a

cost

that

would

be

attractive

to

potential

publishers.

It

should

be

noted

that

although

Dr.

Scatton's

work

is

aimed

primarily

at

teaching

linguistics,

and even more

specifically

Russian,

the

capabilities

he and

his

assistants

found

so

useful

in

the

Terak

can

be

adapted

and used

equally

well

for

practically

any

academic

discipline.

This

is

reinforced

by

Dr.

Scatton's

own

words:

"In

a

single

stroke,

acquisition

of

the

Terak system has

made

possible

an

almost

unlimited

range

of

projects

which

we

could

only

have

dreamed

of

earlier.

There

are

also

unanticipated

benefits

which

the

Terak has

brought.

It

has

served

students

well

by

allowing

them

to

gain

experience

which

will

be

professionally

valuable,

by

opening

up

to

them

the

exciting

perspectives

which computing

Beyond

this,

to

the

computing

activities

undertaken

has

found

its

way

into

our

recruiting

materials,

and

has

attracted

reactions

from

colleagues

in

additon

to

leading

to

increasing

graduate

applications."

During

the

coming

year

Dr.

Scatton's

work

will

continue

along

several

lines

including

(1)

the

inputting

of

additional

texts

for

advanced

Russian

courses;

(2)

designing

more

instructional

modules

in

Russian;

(3)

pursuing

the

feasibility

of

aimed

at

(preliminary

discussions

have

taken

place

other

literary

First

Terak

User's

Group

Meeting

by

Harie

Corbin

On

Wednesday, August

5,

1981

at

ACM

SIGGRAPH

'81

in

Dallas,

Texas, a

not

so

august

body

of

people

met

for

the

First

and Only

Original

Terak

User's

Group

Organizational

Meeting.

It

was on

short

notice,

but

there

was a good

turnout

of

approximately

50

people.

Here

is

a

brief

summary

of

that

meeting:

Discussion

of

Plan

and

Intent

-With

great

intentions

but

little

planning,

it

has

been

decided

that

control

of

the

Terak

User's

Group

will

remain

in

Scottsdale

for

the

first

year.

There

will

be

no

election

of

officers.

Jerry

-Grady,

Supervisor,

Marketing

Software

Support,

will

preside

as

the

User's

Group manager

for

this

first

year.

Terak

Corporation

has

agreed

to

provide

funding

for

this

period

of

time

for

the

User's

Group

operations.

-4-

Some

of

the

goals

for

the

first

year

are

to

obtain

an

official

and

legal

declaration

as

a

non-profit

organization;

continue

to

expand

the

User's

Group

Software

Library;

publish

another

updated Terak

User's

Group

Bulletin

of

Available

Software

(TUGBOATS);

publish

the

newsletter

bi-monthly;

and

write

a

charter.

Formation

of

Special

Interest

Groups

is

desired.

The

following

groups

were

suggested:

Computer Aided

Instruction,

Computer

Aided

Design,

Physics

and

Physics

Education,

Psychology and

Psychology

Education,

Foreign

Languages,

and

Word

Processing.

For

the

first

year,

membership dues

will

not

be

assessed.

Members

of

the

User's

Group

should

consider

how

they

wish

to

support

the

organization,

beginning

with

the

second

year.

Tentative

plans

for

the

second

year

'include

electing

presiding

officers,

establishing

funding,

and

determining

a

more

concrete

direction

for

the

Terak

User's

Group.

Participation

of

Attendees

The

attendees

introduced

themselves

and

stated

their

interest

in

the

Terak

User's

Group.

This

allowed

an

opportunity

for

everyone

to

obtain

information

from one

another

and

determine

common

interests.'

Additional

newsletters,

software

catalogs,

and

membership forms were

made

available

and

all

of

the

User's

Group·Software

was

available

for

copying.

This

was

done

for

several

hours

after

adjournment

of

the

meeting.

For

those

who

were

not

able

to

attend,

we

hope you

can

make

it

to

one

of

the

proposed

three

meetings

to

be

held

this

year

(until

July,

1982).

There

will

be

much

more advance

notice

and

planning

for

these

meetings

and

possible

seminar

presentations

to

TERAK,

PASCAL

EDUCATIONAL

PHYSICS

NETWORK

We

believe

that

a

network

of

TERAK

PASCAL

users

would

be

very

helpful

in:

(1)

Avoiding

duplication

of

effort.

With

some

planning

we

can

share

software

and

avoid

duplicating

the

work

of

others.

(2)

Offer

specialized

services.

For

example

we

here

at

UN-L

have

a

digitizer

and

have

used

an

artist

to

draw

pictures

to

enrich

our

graphics.

We

could

provide

such

a

network

service,

perhaps.

Others

might

have

other

special

capabilities.

(3)

Co-author

physics

lessons.

We

could

define

a

sequence

of

physics

lecture

or

lab

content

and

share

in

the

development

of

the

lessons.

For

example,

Bob

Fuller

and

Dave Winch

are

now

involved

in

a

project

to

develop

24

labs

to

go

along

with

the

main

24

modules

of

our

calculus-based

physics

keller

plan

courses

at

Lincoln

and Kalamazoo.

We

are

working

together

to

prepare

the

lesson

materials

and

coordinate

the

labs.

(4)

Share

existing

programs.

It

is

possible

that

each

of

us

has

already

developed

some

programs

that

would

be

useful

to

others.

(5)

Information

exchange.

Cliff

Bettis,

here,

has

developed

a scheme

that

allows

one

to

chain

pascal

programs

together

and

thus

keep

the

student

from

seeing

the

command

line

between

different

subprograms

of

a

long

pascal

program.

You

may

have

developed

some

utility

programs

that

will

be

useful

to

the

rest

of

us.

We

have

adopted

an

authoring

flow

chart

and

project

organizational

structure

similar

to

those

used

by

Alfred

Bork's

group

(Univ.

of

Cal./Irvine).

We

have

tried

to

develop

a

top

down

structure

for

all

of

our

lessons

and

utilities.

Your comments and

suggestions

are

invited.

At

the

University

of

Nebraska-Lincoln

we

are

interested

in

writing

software

for

computer

assisted

instruction

in

laboratory

physics.

We

use

UCSD

Pascal

(both

version

1.5

and

2.0)

on

dual

density

Teraks.

Because computer

assisted

instruction

programs

tend

to

be

long

we

have found

that

in

spite

of

our

best

efforts

at

memory

conservation

we

run

into

trouble

both

at

compile time

(lack

of

sufficient

symbol

table

space)

and

run

time.

Furthermore,

for

our

project

(which

will

involve

undergraduates

who

have

little

or

no

computer

experience)

we

feel

it

is

necessary

to

keep

separate

our

ultimate

users

and

the

UCSD

operating

system.

So

I

wrote

the

routine

listed

below

to

allow

the

chaining

of

programs

in

the

UCSD

environment.

It

has

been

tested

on

both

the

single

and

dual

density

machines, and

has

proven

non-carcinogenic

as

far

as

the

operating

system

is

concerned.

To

use

it,

compile

it,

write

a

calling

program

(an

example,

CHAIN_TEST

is

given

below) and compile

it

and

link

it

to

the

compiled

unit.

One

can

also

install

the

CHAINER

the

}

Editor's

Note:

In

the

UNIT

CHAINER,

Mr.

Bettis

uses

a

technique

that

is

known

to

most

UCSD

Pascal

hackers

to

access

memory.

This

is

the

RECORD

CASE

structure

as

used

in

procedure

CHAIN.

This

structure

allows

a

user

to

PEEK

and

POKE

memory

contents

easily.

Basically,

a

record

type

is

set

up

that

is

a

variable

case

structure

as

in

RNG_BUFFER.

Part

of

the

case

is

an

integer:

this

is

where

the

address

of

the

memory

location

to

be

accessed

is

stored.

The

other

part

is

a

pointer

to

a

TYPE

that

represents

the

data

in

memory

to

be

acces~ed,in

this

case

a

RECORD

structure

that

is

a

QUEUE.

The

address

of

the

interrupt

service

routine

is

retrieved

(from

the

contents

of

location

48) and

then

a

new

address

is

calculated

using

the

known

offset

of

where

the

keyboard

-10-

input

buffer

is

located.

Storing

this

address

in

the

integer

portion

of

the

variable

case

record

structure,

the

queue can

now

be

accessed

by

pointing

to

the

contents

of

that

address

with

RNG_BUFFER.BUFF;.

This

technique

should

be used

by

only

the

most

serious

of

hackers

that

are

quite

familiar

with

the

memory

layout

of

the

Terak/UCSD

Pascal

OS.]

Question

And

Answer

-

Installing

a

Line

Printer

The

following

is

a

typical

list

of

the

most

often

asked

questions

by

someone

trying

to

attach

a

printer

to

a Terak

Graphic Computer System. These

questions

were

derived

from

frequent

telephone

conversations

with

many

users.

If

your

particular

question

is

not

answered

please

send a

letter

to

the

Newsletter.

It

will

be answered

in

the

If

you have any

helpful

hints

to

add

to

this

list,

please

send

those

as

well.

Q:

I want

to

add a

printer

to

my

Terak.

What

is

the

best

type

to

use?

A:

Choosing a

printer

is

a

very

personal

thing.

All

of

your

printer

requirements

must be

considered:

Do

you want a

letter

quality

printer

(fully

formed

character);

Do

you

want

high

speed

output;

Do

you want

graphics

output

capability;

Do

you

want

different

character

fonts;

What

is

your

price

range?

Write

down

all

your

printing

requirements

and

then

call

one

or

more

local

computer

peripheral

dealers.

They can

provide

you

with

a

list

of

printers,

literature,

specifications,

and

price

ranges

that

will

fit

most

if

not

all

of

your

needs.

Choose a

reliable

dealer

and

don't

forget

printer

ribbons,

paper,

an RS-232

cable,

and

other

accessories.

A

list

of

printers

that

are

known

to

work

with

-11-

Terak Graphic Computer Systems

is

given

in

section

5

of

TUGBOATS.

Q:

What

is

necessary

to

connect

the

printer

to

the

Terak?

A:

Basically

all

you need

is

an

available

serial

port

and an RS-232

cable.

But

there

are

a few more

requirements.

First

your

printer

should

have RS-232

serial

communication

capability.

RS-232

cable

from

the

printer

must

connect

to

the

J1

connector

(DCE)

of

the

serial

port

EIB.

Refer

to

the

Terak

8510/a

Installation

and

User's

Guide

for

correct

orientation.

The

RS-232

cable

is

probably

assembled,

but

for

reference,

pins

2,

3,

7 and

20

should

be

connected

for

use

by

the

Terak.

Pins

2 and 3

are

Transmit

Data and Receive

Data,

7

is

Signal

Ground, and

20

is

Data Terminal Ready (DTR).

Q:

What

are

the

functions

of

these

pins?

A:

2

or

Transmit

Data

is

the

wire

that

carries

the

characters

from

the

Terak

to

the

printer

or

peripheral

device.

3

or

Receive Data

accepts

characters

from

the

printer

or

peripheral

device.

7

or

Signal

Ground

will

help

to

relieve

spurious

noise

on

the

other

Signal

wires.

20

or

Data Terminal

Ready

(DTR)

is

used

by

the

printer

to

tell

the

Terak

when

it

is

all

right

to

send

another

character.

In

some

printers

this

Signal

will

indicate

when

the

printer's

character

buffer

is

full

by

taking

the

signal

HIGH.

Q:

What

is

a

printer

character

buffer

and

when

does

it

get

full?

A:

Almost

all

new

printers

have a

character

buffer.

This

is

a

section

of

memory,

usually

100

to

1000

bytes

long,

that

will

store

unprinted

characters.

The

reason

for

this

is

that

the

computer

usually

sends

information

faster

than

it

can

be

printed.

This

buffer

allows

the

computer

to

send

blocks

of

character

without

waiting

for

the

printer

to

print

each

individual

character.

The

DTR

signal

indicates

that

the

printer

is

ready

to

accept

another

character.

Several

printers

use

this

signal

to

indicate

that

the

buffer

is

full

by

changing

the

signal

from

active

LOW

to

HIGH.

Other

printers

may

use a

different

method

of

indicating

the

buffer

is

full.

Q:

What

might

those

methods be?

A:

It

will

be

necessary

to

check

the

printer's

user

or

operator

manual

to

find

out,

but

one

of

the

most

common

methods

requires

the

printer

to

send

a

character,

such

as

XON

(control

S),

when

the

buffer

is

full

and

then

send a

character,

such

as

XOFF

(control

Q),

when

it

is

ready

to

receive

more

information.

Another

method

requires

the

Terak

to

send a

character,

such

as

ETX,

and

then

wait

for

the

printer

to

send back a

corresponding

ready

character,

such

as

ACK,

before

the

Terak

sends

any

more

information.

Q:

How

does

the

Terak

know

which method

to

use?

A:

Guided

by

the

printer's

manual, you

must choose

the

correct

driving

software.

This

software

is

available

through

the

User's

Group

Library.

For

the

RT-11/85

operating

system,

order

disk

RT3B-80-0005;

for

UCSD

Pascal,

order

disk

PS20-80-0001.

Q:

What

is

on

these

disks?

A:

RT3B-80-0005

contains

the

source

and

system

files

for

several

printer

handlers.

If

your

printer

uses

DTR

to

indicate

buffer

full,

use

LPUNT1.MAC

and

install

the

file

SL.SYS

as

the

printer

handler.

If

your

printer

uses

the

XON/XOFF

protocol,

use

LPXON.MAC

and SX.SYS.

LPETX.MAC

and

SE.SYS

are

the

cor~esponding

source

and

handler

files

for

printing

using

the

ETX/ACK

protocol.

PS20-80-0001

contains

a program

called

PRINTOUT.

This

program

presents

a

screen

menu

with

several

options.

By

typing

A,

then

hitting

-12-

the

space

bar,

a

printer

name

or

protocol

will

appear.

When

the

correct

information

is

displayed,

select

your

by

typing

its

letter.

When

you

quit

PRINTOUT,

save

the

status

of

the

program

to

keep

those

options

you have

selected

for

the

you

execute

PRINTOUT.

Q:

What

about

all

the

switch

settings

that

are

referred

to

in

Appendix F

of

the

Terak

8510/a

Installation

and

User's

Guide?

A:

On

page F-1

is

a diagram

of

the

serial

port

EIB

(External

Inteface

Board) which

is

mounted on

the

rear

of

the

8510.

There

are

two

groups

of

pencil

switches

which must be

set

properly

to

communicate

with

the

printer.

Switches

should

be

set

using

a

paper

clip.

This

ensures

that

the

switch

is

pressed

cleanly

and

firmly.

When

setting

a

switch,

it

should

click

audibly

into

place.

Pushing

in

at

the

top

of

the

switch

will

turn

it

ON

(red

will

show

at

the

bottom).

Pushing

in

at

the

bottom

of

the

switch

will

turn

it

OFF

(red

will

show

at

the

top).

Starting

from

the

left,

use

the

following

switch

settings:

Left

1-0N 2-0FF 3-0N 4-0FF

This

selects

the

serial

port

for

Serial

Unit

1,

which

is

what

the

User's

Group

software

is

preset

to

communicate

with.

Left

5-0FF 6-0FF 7-0FF 8-0FF

This

turns

off

the

serial

port

sense

switches.

They

perform

no

purpose

as

far

as

the

printer

is

concerned.

Right

1-0FF 2-0FF 3-0FF 4-0FF

This

sets

the

communication

mode

to

be 8

bit

characters,

parity

disabled,

TTY

filter

disabled,

and

odd

parity.

In

almost

all

instances

these

settings

will

work

with

the

printer

selected.

If

you

are

using

a

teletype

model

33,

then

you

may

want

to

enable

the

TTY

filter.

The

of

four

switches

sets

the

baud

rate

for

the

printer.

The

following

baud

rates

are

the

most

common:

Q:

How

do

I

test

my

printer?

A:

Assuming you have

followed

the

Terak

installation

procedures

to

check

out

the

serial

line

unit,

and

the

printer

manufacturer's

installation

procedures,

there

should

be

no

problem

connecting

the

printer.

Set

the

serial

unit

switches

as

indicated

above,

plug

the

RS-232

cable

into

the

J1

connector,

and

power

up

the

Terak and

the

printer.

Under RT-11/85, copy

the

handler

you

have

previously

chosen

onto

your

system

disk.

For

example:

COPY/SYS

DK1:SL.SYS

DKO:<ret>

Then

install

the

handler

and

assign

it

as

logical

device

LP.

For

example:

INSTALL

SL<ret>

ASSIGN

SL

LP<ret>

LP

is

the

name

that

all

system

utilities

will

output

to

if

they

use

the

printer.

Then

just

type

DIR/PRI<ret>.

This

will

print

the

directory

of

the

disk.

Under

UCSD

Pascal,

eX(ecute

15:

PRINTOUT.

Type

A

to

choose

the

printer

option,

then

type

the

space

bar

until

the

correct

printer

type

appears.

Type

B

to

enter

a

file

name

and

type

15:HELPFILE(ret>.

Then

type

P.

If

everything

has

been

set

up

properly,

you

should

get

output

on

your

printer.

Possible

troubleshooting

might

include

check

AC

power, check

switch

settings

on

the

printer

and

the

Terak,

and be

sure

the

RS-232

cable

is

plugged

securely

into

the

J1

connector.

Q:

I

am

getting

output

but

it

is

incomprehensible

gibberish.

What's

wrong?

A:

The baud

rate

between

the

serial

port

on

the

Terak and

the

printer

is

-13-

Q:

A:

Q:

A:

not

set

properly.

Check

the

switch

settings

on

the

serial

port

EIB

and

the

printer

baud

rate

setting.

Correct

where

necessary.

I

am

getting

output,

but

after

a

couple

lines,

the

printer

will

lose

characters,

then

start

printing

again,

only

to

lose

more

in

a

couple

lines.

The communication

protocol

between

the

software

and

the

printer

was

not

chosen

properly.

Check

the

printer

manual

again

and

reselect

your

printer

driver

as

outlined

above.

I

already

have

something

connected

to

my

serial

unit

1.

How

do

I

set

the

printer

up

on

a

different

unit

number?

To

have more

than

one

device

connected

to

the

Terak

requires

more

than

one

serial

unit.

Just

because

there

are

3

connectors

on one

EIB

does

not

mean you

can

connect

up

3

devices.

Each

connector

serves

a

different

purpose

in

relation

to

that

1

serial

unit.

A second

serial

unit

must be

purchased

and

installed.

The

only

switch

setting

change from

those

listed

above would be

to

set

the

first

4

switches

on

the

left

set

as

follows:

Left

1-0N

2-0FF 3-0FF 4-0FF

This

selects

the

serial

port

as

serial

unit

2.

The

hardware change

is

easy.

The

software

is

a

bit

more

involved.

The

source

files

for

the

printer

drivers

must be

edited

and

then

recompiled

and

relinked.

Serial

unit

1 communicates

through

memory

register

177520 (177522) and

177524

(177526).

These must be

changed

to

177530 (177532) and

177534 (177536)

for

serial

unit

2.

The

RT-11/85

device

handler

interrupt

vector

must

also

be

changed from 120

to

130.

The

UCSD

Pascal

PRINTOUT

program must be

recompiled

after

the

change

is

made.

Several

other

files

are

included

at

compilation

time,

so have them

available

on

the

Hints

-

Preventive

Maintenance

By

Dave

Delster

Preventive

maintanence on computer

hardware

is

extremely

important

for

the

wellbeing

of

the

entire

system. With

the

Terak

8510/a,

the

user

can perform

easy

maintanence

tasks

which

will

extend

the

life

of

the

Terak

8510/a

considerably.

At

least

once

every

30

days,

the

filters

on

the

rear

of

the

8510

should

be

cleaned.

This

is

easily

accomplished

by

removing and

cleaning

the

filter

with

a

vacuum

cleaner.

To

remove

the

filter,

push

in

on

the

nylon

retaining

ring

and

-14-

rotate

it

clockwise

until

the

four

tabs

have

cleared

the

retaining

slots.

Pull

the

filter

gently

out,

being

careful

not

to

puncture

the

foam

filter.

Use

a good

vacuum

cleaner

to

remove

the

dust

particles.

DO

NOT

WASH

THE

FILTER!

Reinstall

the

filter

by

inserting

the

filter

back

into

the

holder,

pushing

in

slightly,

and

then

rotating

the

filter

counter-clockwise

until

the

tabs

are

locked

into

the

retaining

slots.

Release

the

filter

and

it

will

fit

snugly

into

place.

Every

six

(6)

months,

the

diskette

drive

read/write

head

should

be

inspected

and

cleaned.

The

~

diskette

drive

head

cleaning

diskette

that

is

certified

by

Shugart

&

Associates

is

the

Innovative

Computer

Products

IFD-08. Through

extensive

testing,

Shugart

has

found

that

other

cleaning

diskettes

will

grind

the

read/write

head

down

with

their

abrasive

surfaces.

Below

is

the

necessary

information

for

ordering

the

Innovative

Computer

Products

cleaning

diskette.

If

you do

not

have

access

to

the

FD-08

cleaning

diskette,

then

a

cotton

ball

and

isopropal

alcohol

(91%

m~n1mum

strength)

can

be used on

Single

or

dual

density

disk

drives

only.

This

requires

removal

of

the

disk

drive

from

the

housing

cabinet

to

gain

access

to

the

diskette

read/write

head.

First

remove

the

cover

of

the

8510/8512/8515. With

an 8510

or

8515

it

may

be

necessary

to

remove

the

circuit

boards from

the

back

plane.

Gently

lift

the

pressure

pad

arm

which

is

positioned

over

the

read/write

head.

Inspect

the

pressure

pad

for

Signs

of

wear

or

accumulated

oxidation.

If

this

pad

looks

dirty

it

may

be a

candidate

for

replacement.

While

holding

up

the

pressure

pad arm,

gently

swab

the

read/write

head

with

the

alcohol

soaked

cotton

ball.

Let

the

head

air

dry

for

about

15

seconds

before

releasing

the

pressure

pad arm.

Restore

the

circuit

boards on

the

8510

or

8515.

Replace

the

cover

for

the

8510/8512/8515.
