Installation

Introduction

The following pages cover installation, maintenance, and system testing for the HP 9845B

and

HP

9845C

Desktop Computers. Where similar, the computers are referred to as the "System

45"

or

the

"9845".

Any differences between computers

or

models are noted when necessary.

The following table shows the configuration

for the model numbers which are referred to.

There are other models which are based

on

the model numbers

in

the previous table. The

9845B Model

150, for instance,

is

a 9845B Model 100 with a thermal printer, two tape drives,

graphics,

and

187

K-bytes of read/write memory. For simplicity, this manual refers to Models

100

and

200

only.

If

you have a 9845B Model 150, just remember that your computer

is

referred to as the 9845B Model 100

in

this manual.

Table Mounting

The System

45

mainframe can

be

attached to a table top by replacing each foot with an

internally threaded device

and

bolting up through the table top. Bolting the main frame to a

desk which has a lockable drawer secures the computer from theft. Care must be taken

in

laying
out the bolt holes so that the front edge of the computer overhangs the edge of the table top.
This ensures that the air filters can

still

be removed and cleaned.

The computer can

be

secured to the top of a table or desk

in

the following manner:

•

Drill

four holes in the top surface of a table to accommodate 5/16-24 NF-2A screws

according to the following diagram.

• Replace the four rubber feet attached to the bottom of the computer with the four hex­agonal spacers supplied with the Table Mounting Accessory

(P/N 09845-61201), using the

6-19X.

438

Pan Head, Pozidrive, Plastite screws, also supplied.

• Attach the computer to the table top, using four 5/16-24 NF-2A machine screws that are
3/8 inch longer than the thickness of the table top. The hexagonal spacers should

be

held
with a wrench while these screws are tightened to prevent stripping the smaller screws out
of the plastic base.

• The keyboard should extend

8.25

inches

in

front of the table top, as shown, to make the

air filters accessible for periodic cleaning

or

replacement.

Installing

the

CRT

The System

comes equipped with a CRT (Cathode Ray Tube) display. The eight keys

directly below the CRT screen on the

98458

Model

200

and the

9845C

are called softkeys. The

"CRT pull-out cards" (under the CRTj serve as a handy reference for operating the computer.

Installing the

98458

Model 100

CRT

I

Align

the guides on the CRT assembly with the mainframe support legs, as shown here. Notice

that the buttons on the bottom of the CRT assembly align with the notches

in

the support legs.

After careful alignment, allow the CRT to rest on the support legs.

To remove the CRT, press the CRT release buttons and pull up.

Working

on

one

leg at a time, tilt the display slightly to the right

and

gUide

the right leg into

place. Pull the display to the left toward the other leg, and position the left leg into place.

The back of both display legs should now

be

resting on the top cover of the mainframe. (If not,

check both sliding lock handles - they should

be

pulled out.) There should

be

a gap (about %

inch) between the mainframe top cover and the front of the display legs. If the display does not
appear

ensures proper contact with the mainframe.

Now push the sliding lock handles in, to secure the CRT to the mainframe.

To remove

the

CRT, pull the sliding lock handles out and

lift

the CRT straight up. (Remember

that two people are needed to

lift

the color display.)

CRT Intensity
Once the System

System

Exerciser

The programs

on

the System Exerciser Cartridges (HP PIN 09845-92041 Revision C

and

09845-92042

Revision

A)

are designed to assure you that the System

45

is

operating properly,

and

if

it

is

not, to identify problem areas which may exist.Some exercisers require that you

compare what

is

displayed

or

printed to what

is

described

in

this manual.

All

of the exercisers

display error messages when errors are detected.

If any exerciser should

fail,

please note the error

and

refer to Section 4, Troubleshooting.

The exercisers are divided into three types: internal mainframe. peripheral,

and

interface.

The

internal mainframe exercisers should be run first to exercise the System

45

mainframe thor­oughly before running any of the external peripheral or interface exercisers. Refer to the
appropriate chapter

of

this handbook for interface

and

peripheral exercisers.

Turn-On

Self

Test

When the

9845

is

turned on, a self test occurs. The processors go through a test routine,

if

successful, the

9845

will

beep

at least once. The numbers of beeps isn't important.

The

proces-

sors also check to see the type of CRT they'll

send

display data to,

and

determine which

processor

is

PPU/LPU. A CRT must be attached for this processor

10

routine to finish,

if

none

is

connected, the processors hang up, the

9845

appears dead.

Next,

RWM

is

tested to ensure at least 16K bytes exists

in

block 0,

and

tests graphics

RWM

if

graphics

is

installed. The graphics raster may be seen flashing different patterns during the

graphics

RWM

test, followed by "MEMORY TEST

IN

PROGRESS"

on

the display. Normally,

the CRT circuits may not

be

warmed up enough for the graphics

RWM

tests to be seen. Should

errors

be

trapped

during the

RWM

tests, the CRT should display "PART OF MEMORY FAILED

SELF-TEST".

The

amount

of

RWM

that's lost can be determined by executing LIST

and

comparing available

RWM

with the

amount

of

RWM

the

9845

should have.

When the turn-on tests are successfully completed, the display should read:

"9845

READY

FOR USE". If AUTOST

had

been

latched,

and

a tape inserted in T15, the tape should rewind

and

load the AUTOST program

and

run

it.

Refer to the

9845B/C

Mainframe Troubleshooting, Section 4,

if

this test has errors

or

fails.

Exerciser Starting Procedure

Before starting, use the following checklist to ensure that the 9845B/C

is

ready for testing.

• Switch

power

off.

•

On

the back panel, check to ensure that the line voltage selector switches are set,

and

that

the correct fuse(s)

is

(are) installed.

• Verify that

the

ROMs

and

interfaces are properly installed.

Latch the

AUTOST key

on

the computer. Begin by inserting System Exerciser Cartridge

#1

in

the right-hand

tape

drive so that the cartridge label faces up

and

out. Switch on power to the

System 45,

and

the computer should load

and

run the supervisory exerciser program. If this

does

not happen,

or

if

a blinking cursor does not appear on the CRT within

about

20

seconds

after turn-on

and

cannot

be

obtained by pressing CONTROL STOP, refer to Section 4, Troub-

leshooting.
The supervisory exerciser program can also be loaded by typing

LOAD

11

AUTOST:

T

15

11

and

pressing EXECUTE.

When the supervisory exerciser program begins to run, the following information

is

displayed:

SYSTEM

EXERCISER

Do

YOU

want

PRINTED

output

(Y,N)?

Answer Y for yes or N for no. and press CONT. If you want the printout to

appear

on the CRT,

answer no.

If you answer yes, you are asked to:

Please

enter

the

PRINTER

select

code

•••

For non-HP-IB printers, enter the interface select code. (Enter 0 for the internal printer.)

If you have an HP-IB printer. answer with the select code

and

the device address entered

together as a three

or

four digit number. The interface select code can be a

one

or

two digit

number

which represents a valid select code. The

deVice

address must be a two digit number.

For example, a 9871A

Printer (HP-IB option only) connected

on

interface 7 with its address set

to 6

is

entered

as

"706".

(Secondary addressing of HP-IB devices

is

not allowed.)

The choices of exercisers for System Exerciser Cartridge # 1 are then printed on the specified
printer (or

the

CRT).

An

asterisk

(*)

appearing before any of the

MAINFRAME

exercisers shows that that particular

option

is

not installed.

Use the

same

procedure to run the exercisers on System Exerciser Cartridge

#2.

Now select

and

run exerciser(s) as explained on the

follOWing

pages.
