HARDWARE CONFIGURATION
Hardware
Overview
The TS 806/20 is
a
tabletop
computer which
contains the
following
components:
One
51
/4
-inch Winchester
hard
disk
drive
One
51
/4
-inch
floppy
disk
drive
Specification
details
are
given in Appendix A.
The
TS 806/20
will
be referred to as
the service
processor.
Disk
Drives
The TS 806/20 has
one 5
1 /4
-inch Winchester
hard
disk
drive
and one 5
1 /4 -inch
floppy
disk
drive.
The floppy
disk
drive is located
on
the
left
side
of
the
computer.
(See
Figure
1-1.)
The
Winchester
disk
drive is
located
immediately
to the right
of
the floppy
disk
drive.
Hard
Disk
and Floppy Diskettes
The
hard
disk
is
permanently
sealed
in an air
-tight
enclosure and is
not
accessible to
you.
It
has a
capacity of 19.14
megabytes
of
unformatted
disk
storage
(formatted
15.04
megabytes). Data
can
be
stored
on
this hard
disk
and accessed by
all user
stations
connected to the TS
806/20.
The floppy
diskettes are 5
1
/4
-inch,
double
-sided,
double
density
with
a
capacity of
500
kilo-
bytes
of
unformatted
storage
(formatted 368.6
kilobytes). Figure
1-3 shows the floppy
diskette.
Figure 1-3
Floppy
Diskette
Each
diskette
has a magnetic
coating
on
both
sides,
much
like a
phonograph
record. Unlike a
phonograph
record,
it
arrives
in
a
protective
black
plastic
cover
which
is
NOT
removable.
Lubri-
cants inside this
cover
increase the life
of
the diskette. The
actual
diskette
can
be
seen
through
some
of
the slots
in
the
plastic
cover.

INTRODUCTION
Figure
1-4
shows the
actual
floppy
diskette and protective
lining inside the
plastic cover.
When
cared
for properly
(as described
in Chapter
5), diskettes
can be used
many
times.
The TS 806/20
can use
any
floppy diskette
which
meets the
specifications
given
in Appendix F.
New diskettes
must be formatted
before data
can
be
stored
on them
(as
explained
in 5.2.2).
Figure

Diskette Inside
Permanent
Plastic
Enclosure
Applications programs,
text,
data,
and programs
which
operate the TS
806/20
can
be stored
on
either
the
hard
disk or
floppy
diskettes.
1.3.4
Peripheral
Devices
The
ports
on
the
rear
of
the TS
806/20
allow
you to
connect
a wide
variety
of
peripheral
devices.
Up to
six
user
stations
can
be attached
to the TS
806/20. These
user
stations
may
(but
do
not
need to) have
their own
data
storage.
In addition
to the
user
stations, a
service
processor termi-
nal
is used to
run utility
programs,
run
service diagnostics,
modify
the
operating parameters
of
MmmOST,
and
monitor
the
operation of
the TS 806/20.
A user
station can
also
operate as a
service
processor terminal
by
changing
the
switch setting
on
the
rear
panel. Refer
to
the opera-
tor's
manual for location
and
settings
of
the
switch.
Optional
peripheral
devices
can
be
shared by
all user
stations.
For
hardcopy
output,
you
can
connect
a
serial printer
to the
port
labeled
RS232
[OPT].
(This could
be a
dot
matrix,
line,
or
letter -quality
printer.)
This interface
is compatible
with most RS232
-compatible
serial
printers
currently
available
on
the
market,
including both character
-by
-character
and
buffered printers.
A serial
device,
such
as a
modem, can
be attached to the
RS232
[OPT]
port
instead
of
a
printer.
You
can attach
a
parallel
Centronics -type
printer
to the
port
labeled
PRINTER.
Refer
to Figure
1-2
where
several
possible
configurations are illustrated.
D
The
peripherals described here
are
all in
addition
to
those
which
maybe
connected
directly
to
each user station.

SOFTWARE
OVERVIEW
Operating System
Every
computer
needs instructions
in
order
to
operate;
these
instructions are
supplied
by
a
group
of
programs
collectively
called
the operating
system.
When
the TS 806/20
is
turned
on,
its
operating
system
is
loaded into memory from
the
hard
disk
and
then
into the
memory of each user station
which
is turned
on. All
TeleVideo
computers use
CP/M
(Control Program for
Microcomputers)
Operating
System
software,
developed by
Digital
Research .
D
If
you
are
not
already
familiar with CP/M,
TeleVideo
highly
recommends
that you
refer
to the
reference books listed
in Appendix
C
and
become
familiar with
the basic
operation of
the
CP/M
operating system.
When
the TS 806/20 is
used
in
a
multiuser
environment, it
also uses a
special
program
called
MmmOST. MmmOST
is
an
acronym for Multiuser,
multiprocessor, multitasking
Operating
Sys-
tem
Technology.
MmmOST
controls
access
by the
user
stations to the files and programs
stored
in
the TS 806/20.
1.4.2
Programming
Languages
User
stations
can
use
any programming
language
which will run
under CP/M.
Among
these are
BASIC, ALGOL,
APL,
"C,"
COBOL,
CBASIC,
FORTH, FORTRAN,
MBASIC,
PL/I,
and
RM/
COBOL.
When
these
languages
are used
with
MmmOST,
modifications
which
are
described
in
the
MmmOST
Programmer's
Manual allow them
to take
advantage
of
the
features
of
MmmC~ST. In addition,
TeleVideo
COBOL
allows
applications
programs
to be used
with
MmmOST
with
little
or
no
modification.

tasks,
from accounting
to
security. In
addition,
you may
write
your own
applications
programs
in
one
of
the
programming
languages
compatible
with CP/M.
Applications programs are
normally
run in
the
user
stations,
not in
the
service
processor.

2.3.2
Physical
Requirements
The TS
806/20 and
user
stations
should be
within
300
feet
of each
other.
The
service
processor
terminal
should be
within
50
feet
of
the TS
806/20.
A serial
printer
should be
within
50
feet of
the
TS
806/20.
The
parallel
printer
(Centronics
-type)
should
be
within
10
feet of
the
TS
806/20.
Refer
to the
printer
instructions
for
recommended
distance.
Leave
at least
four
inches
of
free
space
around the
enclosure
for
proper air
flow.
Place
the
TS
806/20
on
a
sturdy,
flat,
level
surface.
The
dimensions
are
given in
the
specifications
in
Appendix A.
2.3.3
General
Environment
2.3.4
The
TS
806/20
will operate
best at
temperatures
and
humidity levels
in
which
you
are
also
com-
fortable.
Sudden
and
drastic
temperature
changes may
adversely
affect your stored data.
The
system
requires a
clean
environment
free
of contaminants
such
as
dust,
carpet fuzz,
and
smoke.
Excessive
moisture
or oil particles
in
the
air will
hinder
the
performance
of
the
system.
Keep the
system
away
from
the
floor
where
dust
or carpet
fuzz
would be
more
likely
to
get
into
the floppy
disk
drive.
Magnetic
Isolation
For
optimum performance, locate
the
system at
least
five
feet
from other
computing
equipment,
any
electrical
appliances,
or equipment
(such
as
elevators,
radio
transmitters,
and
television
sets)
which
generates
magnetic fields.
2.4
INSTALLATION
General directions
for all
installations
are
given in
this
section.
The
next
four subsections
give
directions
for
connecting
the
following
peripheral
devices:
1.
Up
to
six
user
stations
2.
A
service
processor
terminal
3.

2.4.1 Cables
To
connect
the TS
806/20
to a
terminal,
user
station,
printer
and
any
other
peripheral
device
(such
as
a
modem),
you
will
need
cables. The
quantity and
types
of
cables needed
are
deter-
mined
by the
number
and
types
of devices to be
attached.
Your dealer or
distributor
can
supply
you
with
the
appropriate
cables. The
technical specifications
for each
type
of
cable are
shown
in
Table
2-1. Refer
to
Appendix G
for
more detailed
cable
specifications.

is
not
placed next
to
electrical
devices
or
cables that
could
induce
electrical
interference into
the ribbon
cable.
Cable
connectors
commonly
have
D
-shaped
end
connectors
(Figure
2-1).
These fit
onto a
D
-shaped
pin
connector
on
the
rear
panel
of
the system.
To
install
a
cable,
turn
the
connector
end
to
fit
the
pin
connector on
the
device,
then
gently
but
firmly
push on
the connector.

Cable Connector
As
you connect
the
cables,
leave
some
slack. If
you
have
excess
cable
left, coil
it
loosely
and
secure
it with
a
rubber
band.
Place the
cable out
of
the way.
D
I f
you are
using
a
ribbon
cable, do
no
t roll
up
the
excess cable.
Rolled
ribbon
cable
looks nice
bu
t
it
creates
an
inductor
or
choke
which can
adversely
affect system
performance.
Excess
ribbon
cable
should be
folded
accordion
-style
as
shown
in
Figure
2-2.
