Introduction
Logging failure.
It is important to log details of
failures, and solutions found.
If the ansver to a fault 1s still being
sought, it is important for you to note
the syaptons and the actions you have
taken to try to solve the proble.. The
notes will help if specialiat aasiatance
1a eventually needed.
If you have not .. naged to aolve the
proble. on your first visit, then any
notea you .. ke of the syaptona you found
or were told about by the user, and the
action you took, .ay be very uaeful
later, either to you or to a apecialist
called in to help.
A good way to log theae failure reports
1a to write the. up on J-part stationary
(auch a. ICL self carbon internal A4
.e.os). One part you can file in Section
8 in this guide, one part you can leave
on aite with the ayate., and one part
perhaps you could aend to u. (aee

Cautions

So.. components on printed circiut Doards can be
damaged by excessive voltages, regardless of
current flow. Such component. are referred to a.
electrostatically sensitive device. (£SDs). To
avoid damage to such devices froa aoveaent
generated charged on the body:
• avoid unnecessary handling of boards
• wear an earthed vrist strap when handling boards
• always transport boards in an authorised
container
• keep board in container until required
• slit the coritainer with a knife, do not tear it
open
• if they are supplied, carefully remove edge
connector shunts and reapply to the replaced
board.
Screen optical caatill9s

Some video terminals have a special anti-olare
coating applied to their screens. Try to avoid
fingering these screens. If a screen is
contaainated by oils fro. the skin, use only the
reeo. .ended cleaning pads to remove the oils and
vipe the screen dry with a soft paper tissue or a
lint-free cloth.
Pield repair strateoy
Board or whole unit replacements are the expected
.ethods of on-site repairs to equi~ent covered by
this guide. Sub-unit replace.ents vill noraally be
done by service centres, only in unusual·
situations will subunits like .ains transformer.
• and cathode ray tub•• be replaced on site.
Pised disc damage
On Tl ..chine. lock the disc heads before aoving
the proc..sor be careful not to jar the unit if it
has to be moved to gain accedss to the locking
.echani •• at the rear of the unit. On T2 ..chines
the 5.25 inch disc heads are not locked manually.

Dau corruption
Failure to observe the following can result in
syste. data being corrupted.

surface

• Do

not stand the display unit on top of the

• Do

• Do not place the tablet biasing .agnet on or

This subsection should help you to isolate
problems to do with the power distribution.
2.2.1

AC distribution
If power is present at the processor unit and the
circuit breaker is closed, the fans wll·1 be
running.
If the fans run but DDS is not lit, check the a 5 c.
power connection to the PSU.
Consider that some monitor units have an internal
PSU and will therefore have a seperate mains input
require..ent.

2.2.2

DC distribution
Take off the rear panel of the processor cabinet.
Measure the DC voltages at the supply except +24V
and +55V which are measured at the bulkhead.

supplied, depending upon syste. require.. nt.
The Su...grapbics tablet unit consists of, a 4button puck and interconnecting cable. A marking
or non-marking stylus is also a.ailable as an
optional feature.

The tablet has a magnetic field and flopPr discs
must not be placed on the surface.
Tbe tablet logic circuita are contained on a PCB
under the tablet surface. Tbese circuits are based
on an 8035 micro-co~uter syste. and a 50 ..gaberta counter.

Magnetostrictive wa.es transaitted through a wire

The cable is usually .arked at 2.5 setre intervals

to ensure that reflection levels are acceptable
after in.tallation.
The cable screens for each network aegaent are
earthed at one point only and rubber boots are
fitted to any connector bodies to avoid accidental

4.19.2

PBX operating syste.: general information
The ICL PNX operating syste. is a developeent of
Bell Laboritories UNIX for use with PERO hardware.
The UNIX syste. is written in C language and
widely used on a Variety of co~uter hardware
i~le.entino a C code interface. A PERO microcode
executes C code instructions wbch are oenerated oy
the C langUage ca.piler.

TIle-PNX system has a:
• tree structured filestore and provides
coeprehensive file handling facilities
• powerful and versatile coamand language
The .ajor features specific to PNX are:
• window manager, for the PERO hiOb definition
display
• virtual store, for the execution of large
progra..
• device drivers, for PERO hardware and devices
connected to the GPIB and RS232 interface.

Co...nds can De input from the keyboard in
reapon.. to a coamand line prompt. The two prompts
are:
$ for norasl uaers

• for auperusers

A superuser has access to all the files in the
syste.. a normal user has only restricted acce••
to the file.tore.

Command lines have the form:
COmMand [-flags) [argu.ent]
For example the following command line lists all
the files in a directory called user oivino full
details
la -i /user

Section 5.2 oives an outline of PNX syste.
operation. Full information is provided by the ICL
PERQ: Guide to PNX (RPIOI03) in conjunction with
the UNIX Programmers manual (RPI0125, RPI0126 and
RPI0127).
