While a diagnostics program

is

executed,

[[0]]

to

[[9]]

of

the

typewriter

keys

function

as

data

keys

irrespective

of

[[Shift]].

For example, even if

[[1]]

is

entered

while

the

shift

key

of

the

typewriter

keys

is

pressed,

numeric

data

[1]

is

entered.

(3.2) Hexadecimal Code

Entry

Codes from [0]

to

[9] can be

entered

in

the

same

manner

as

the

decimal numbers; codes

[A],

[B],

[C],

[D],

[E],

and

[F.]

should

be

entered by using

[[A]]

to

[[F]]

of

the

typewriter

keys.

Like

the

decimal

code

entry,

while

a

diagnostics

program

is

executed,

[[A]]

to

[[F]]

of

the

typewriter

keys function

as data keys irrespective

of

the

state

of

[[Shift]].

For

example,

even if [a]

is

entered

while

the

shift

key

is

pressed, code [Al

is

entered.

of

Control

After

the

LOADER

is

started

up,

it

controls

the

system.

The

LOADER requires

the

selection

of

each condition

and

one

of

the

DIAG programs. When

the

user properly makes

such selections,

the

LOADER loads

the

test

and

data

of

the

DIAG program from

the

floppy disk

to

the

memory

of

the

personal

computer

and

then

transfers

the

control

to

the

DIAG program.

After

that,

execute

the

DIAG program in

the

operation

procedure described

in

the

manual

of

each device.

When control exits

to

(that

is,

is

and

relating

Ie

occurs.

(2.3) Aging [Marching and

ADCOMP]

.

(2.3.1) Outline

This

program

serves

as

an

aging

test

for

the memory.

It

alternately conducts marching test

and

address complement

test.

For details

of

the program,

see

Paragraphs (2.1) "Marching"

and (2.2) "Address Complement".

(2,3.2.) Operation

When

specifying this test, enter the proper data

to

prompts

displayed sequentially

as

shown

in

Figure

MEM-4.

(a)

Test

(a.l) Specification of Error Stop

Error

[0: Yes, 1:

NoJ

=

I\l

If

an

error

occurs while conducting the test, specify

whether

to

abort or continue the test.

(a.2) Confirmation of Test Execution

-------------------~-----

Test

start?

[0:

Yes,

1:

NoJ

=

I\l

Confirm whether

to

execute the test or not.

When entering

[[1

J],

the test can

be

conducted from

"Specification

of

Error

Stop" mentioned

in

(a.1).

On

the

other hand, when entering [[OJ],

the

system displays the

screen

as

shown

in

Figure

MEM-4

and starts the test.

The system displays the current

area

and total

area

in

hexadecimal notation on the lower portion

of

the screen.

Test mode: Marching

Pass

count

[Ox]

=

~1\l~1\l

Current area [OxJ =

I\ll\ll\ll\ll\l

-

~I\ll\ll\ll\l

Total error

[Ox]

=

I\ll\ll\ll\l

The test mode represents the currently executing mode

(Marching, Address complement). The pass count repre-

sents the number

of

times

of

test pass.

The current

area

represents the

area

being tested

in

the unit

of

4

KB

physical address. The total error represents the

number

of

times

an

error

occurs.

(2,3.3) Abortion and Completion

of

Test

PC-7000A

PC-7100

Although [[ESCJ J and

[[F2J]

are available while

the

test

is

conducted, a time

lag

occurs because these key opera-

tions

are

processed

in

the state where the executing pro-

gram

step

is

completed.

By

pressing [[ESC] J, control exits

to

the

MEM

test

menu

(Figure MEM-ll.

By

pressing

[[F2)],

the system displays the following

message on the lower left screen and aborts the test.

"Test stopped by user."

At

the

time,

by

pressing

[[Fl

J

J,

the system continues the

test;

by

pressing [[ESCJ

J,

control exits

to

the

MEM

test

menu (Figure MEM-l).

Whenever one test

is

completed, the system increments the

pass

count and repeats the test.

(2.3.4) Error Processing

When

the total error

is

zero,

the

system does not

detect

an

error

in

the test.

On

the other hand, if the system detects

an

error, it displays the following error message on the

error

message field.

"Memory error! !"

In

addition,

it

the

Error

Stop

is

set

to

"Yes", the system

displays the following message and aborts the test.

"Test stopped !!"

If

the

Error

Stop

is

specified

to

"No". the system displays

only the preceding message and continues the test_

(3) Decision Standard

The system represents a compare error unless the total error

is

"0" when the test

is

completed_

If

the

system detects an

error,

it

displays the address, data, and the relating

Ie

number where the

error

occurs.

All

addr~sses

being displayed

are

physical addresses

of

the

memory.

CD

circuits.

By

turning

ON/OFF

the

DTR signal,

the

system reads these

states by means

of

the

CI

and

CD

and

tests them. If

the

system detects

an

error,

it

displays

the

following message.

(2.2) FDD Write, Read & Compare

(2.2.1) Outline

This program serves

to

check that the write/read operation

is

properly performed

in

such a manner that the system

writes data to the floppy disk, reads the same data from the

floppy disk, and then compares them. (The data

to

be

written

is

00

to

FF

increment pattern when

the

number

of

times test pass

is

000; otherwise the data

is

4-byte

repetitive

pattern of "EB6DB6DB".)

The program causes

all

cylinders from

01

to

39

to

be

tested.

(a.3) Specification

of

Counting Sectors

Specify

the number

of

counting sectors capable

of

being

processed

by

If

other value which

is

not displayed

is

entered,

the

system

does

not

accept such a value and

req~ires

proper data entry

once

again.

When pressing

[[all

IbA) Abortion and Completion

of

By

pressing [[ESCII while

the

system executes the test,

control exits to

the

test

menu (Figure FDD-1); by

pressing

[[F21I,

the

system displays

the

following message

on the lower left screen and

stops

the

test.

"Test stopped by user."

At the time, by pressing

[[Flll,

the system continues

the

test. Whereas,

by

pressing

[[ESCII,

control exits

the

FDD.

test menu (Figure

FDD·l).

(c)

Error

Processing

If

the system detects

an

error after it

conducts

the test until

it starts the seek operation, it

stops

the

test

irrespective

of

"Yes"

Or

"No"

of the error stop described

in

(b.2). At the

time, when pressing

[[ESCII,

control exits

to

the FDD test

menu (Figure

FDD·l).

If

the system

detects

an error while it

conducts

the read

check test,

it

displays the

command

parameter and status

where

the

error occurs (Figure FDD-4) and increments

the

right-hand error counter.

If

the

Error

Stop

is

set

to

"No",

the system updates the error

counter

every

time

an

error

occurs and continues the

test

(the

syst~m

only

displays

the

newest error information).

On the other hand, while

the

error

stop

is

set

to

"Yes",

the

system stops the

test

if an error occurs.

At

the

time,

when

pressing

I[

~)],

the system

continues

to

conduct

the

test. Whereas, when pressing

[[ESCII,

control exits

to

the

FDD

test menu (Figure FDD-l).
