1. INTRODUCTION
1.1 INTRODUCTION TO THIS MANUAL
TeleVideo's TS 802H is acompact tabletop microcomputerwhich can be used as astand-alone
computer, user station,
or service processor terminal connected to amultiuser system (either a
TeleVideo TS 806
or TS 816). Many peripheral devices (printers, teletypes, modems, etc.) can
be used with the TS 802H, ensuring maximum flexibility.
When the TS 802H is auser station for aTS 806
or TS 816, it shares with other users the disk
storage, printers, and other peripheral devices attached
to the central system. Since user pro-
grams run
in the TS 802H's internal processor, the performance of the central and local system
is maximized.
This manual will show you
how to successfully install and use your new TS 802H regardless of
your past experience with computers.
Ifyou are using
yourTS 802H as auserstation with aTS 806 orTS 816, referalso to the TS 806
or TS 816 Computer System Installation and User's Guide.
Every attempt has been made
to present all of the information you will need in acomplete and
easy-to-understand manual. Your comments about the manual are welcome.
To facilitate this,
we have provided aReader Comment Card. Please take amoment to complete and return the
card
to us after you have finished installing your system.
1.2 LIMITED WARRANTY
The TS 802H is covered by alimited warranty. The terms and conditions of the complete limited
warranty are provided
in Appendix B.
1.3 HARDWARE CONFIGURATION
1.3.1 Hardware Overview
The TS 802H is atabletop computer which contains the following components:
•One 51/4-inch Winchester hard disk drive
•One floppy disk drive
• A TS 800 logic board
• A
"daughter" board containing floppy controller logic and aWinchester drive controller
board
• A terminal with the capabilities
of the Model 950
• A Z80A microprocessor
•64K
of RAM memory
• A
4K EPROM for diagnostics
The floppy disk drive uses 5 1/4-inch double-sided, double-density floppy diskettes (also called
minidiskettes) with acapacity
of 368 kilobytes disk storage. The Winchester disk drive has a
capacity
of 7.4 megabytes of disk storage. The total formatted capacity of the system (with the
hard and the floppy disk drives) is 7.768 megabytes.
The microprocessorwithin theTS 802H will be referred to as the internalprocessor. All I/O ports
operate through this internal processor, enabling you
to use all standard CP/M function
commands.
1-1

1. INTRODUCTION
The integral terminal has anonglare screen and detached Selectric-style keyboard for the com-
fort
of the user. Deluxe terminal features such as special graphics, visual attributes, and pro-
grammable function keys provide additional flexibility.
1.3.2 Disk Drives
The TS 802H has one hard disk drive and one floppy disk drive.
Much like aphonograph, each floppy drive has ahead
or arm which is lowered onto the disk or
diskettewheneverthe drivedooris closed, enabling the system
to read or write information. The
disk head can move back and forth
("seeking") as required to scan for information. The floppy
drive is located behind the dooron the upper lefthand side
of the front of the case (Figure 1-1).
The head on the Winchester hard diskfloats overthe disk on acushion of air whenever poweris
on. The hard disk drive is located immediately below the floppy disk drive.
1.3.3 Disk and Diskettes
Application programs, text, data, and the programs which operate the TS 802H are stored on
the hard disk and floppy diskettes.
The drive heads automatically read both sides of thefloppy diskettes(Figure 1-2). The TS 802H
can use any floppy diskette which meets the specifications given
in Appendix C. Newdiskettes
must be formatted before datacan be stored on them (as explained
in 3.2.1 and Appendix M).

Permanent Plastic Enclosure
Each diskettehas amagneticcoating on both sides. Lubricants insidethis coverincreasethe life
of the diskette. The actual diskette can be seen through some of the slots in the plastic cover.
Figure 1-3 shows the actual floppy diskette and protective lining inside the plastic cover. When
cared for as described
in Chapter 4, diskettes can be reused many times.
When you insert the diskette
in the drive and close the door, the drive spins the diskette (inside
thecover). Dataare stored on tracks
in concentricrings on thediskette. The small opening in the
diskette cover near the center hole is areference point for the head while locating data. The
oblong opening
in the diskettecover allows the head to retrieve information in batches.
1.3.4 Peripheral Devices
Three ports on the rear of the TS 802H allow you to connect peripheral devices as described in
Table 1-1.

This RS232C
port is for auser-supplied serial device such as a printer or amodem. This
port is configured for aprinterwhen shipped from the factory, butcutting traces and making
jumperconnections allows amodem
to be connected to this port instead.
This RS232C
port may be configured in any of three ways:
1. When shipped, this port is configured for use with amodem.
2. Cutting traces and making jumper connections allows the TS 802H to be used with a
serial printer.
3. Changing adipswitch allows the TS 802H to be used as aservice processor terminal
with the TS 806/816 system console port.
This highspeed serial
port connects the TS 802H to the TS 806 or TS 816 for use as a user
station.

1. INTRODUCTION
1.4 SOFTWARE OVERVIEW
1.4.1 Operating System
Every computer needs instructions in order to operate; these instructions are supplied by a
group
of programs collectively called the operating system.
Using dipswitches on the rear of the case, you can select one of three ways for the operating
system
to be loaded intotheTS 802H, as described in Table 1-2. When theTS 802H is used as a
stand-alonecomputer, its operating system can be loaded into memoryfrom afloppydiskette
or
fromthe hard disk. When the TS 802H is auserstation foraTS 806/816, theoperating system is
loaded from the TS 806/816. Table 1-2 shows the drive assignments for each configuration.

Notes
1. Excluding directory and operating system allocation
2. Simulated floppy drive
3. Expandable to 1024 using CBIOS
All TeleVideo computers use CP/M (Control Program for Microcomputers) Version X.X Operat-
ing System software, developed by Digital Research.
If you are not already familiar with CP/M, TeleVideo highly recommends that you refer to the
recommended reference books listed in Appendix Dandbecome familiar with the basic oper-
ation
of the CP/Msystem.
1.4.2 Programming Languages
The TS 802H can use any programming language which will run under CP/M. Among these are
BASIC, ALGOL, APL,
"C," CBASIC, COBOL, FORTH, FORTRAN, MBASIC, PL/I, AND
RM/COBOL. When these languages are used with MmmOST, modifications which are de-
scribed
in the MmmOST Programmer's Manual allow them to take advantage ofthe features of
MmmOST. In addition, TeleVideo COBOL allows application programs to be used with
MmmOST with little
or no modification.
1-5

1. INTRODUCTION
1.4.3 Application Programs
Application programs are commercially available for awide range of tasks from accounting to
security. In addition, you may write your own application programs in one of the programming
languages compatible with CP/M.
Programs written specifically to take advantage of the features of terminals other than Tele-
Video's Model 950
may need to be modifiedsince the integral TS B02H terminal functions the
same as aModel 950.
1.5 USING THE MANUAL
1.5.1 Organization
Chapter 2will show you how to unpack and install the TS B02H. Chapter 3will describe how to

2.3.3 General Environment
The TS 802H 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 aclean
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 drives.
2.3.4 Magnetic Isolation
Foroptimum performance, locate the system at least five feet from othercomputing equipment,
any electrical appliances,
or equipment (such as elevators, radio transmitters, television sets)
which generate magnetic fields.

2. INSPECTION AND INSTALLATION
2.4 INSTALLATION
General directions for all installation configurations are given in this section. The next four sub-
sections give directionsfor installing a
serial printeror modem (or otherperipheral serial devices)
and connecting the T8 802H (1) to aT8 806 or T8 816 as (a) aservice processor terminal (ser-
vice console) or (2) auser station.
2.4.1 Cables
To connect the T8 802H and acentral computer, printer, and any other peripheral device (such
as a modem), you will need cables. The number and types of cables needed are determined by
the numberofdevices attached to the T8802H. Your dealer can supply you with the appropriate
cables.
(The technical specifications for each type of cable are shown in Appendix E.)
Cable connectors commonly have D-shaped end connectors. These fit onto aD-shaped pin con-
nector
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.
Figure 2-3 Cable Connector
As you connect the cables, leave some slack. If you have excess cable left, fold it loosely accor-
dion-style
(being careful not tocrimp the cable) and secure it with arubber band. Place the cable
out of the way.
Figure 2-4 Correctly Folded Excess Cable
2-4

2. INSPECTION AND INSTALLATION
If you are using aribbon cable, do notroll up excess cable. Rolled ribbon cable looks nice butit
creates an inductor
or choke which can adverselyaffectsystem performance.
Also plug the keyboard cable into the rear panel.
2.4.2 Power Configuration
The system will be configured for your power requirements at the factory (either 115 or 230
VAC). Athree-prong plug
is provided. If you use it with an adapter, ground itwith a"pigtail." The
powercord wires are color-coded as follows:
Green Earth ground
Black Primary power(hot)
White Primary power return (neutral)
2.4.3 Using the TS 802H as aStand-Alone
If you use the TS 802H as astand-alone computer(Le., not as auser station for aTS 806/816),
nocable connections are necessary unless you wish
to connect printers and/or modems to the
TS 802H. Check settings for S2 dipswitches as described
in Appendix G.
2.4.4 Connecting the TS 802H as aService Processor Terminal
Toattach the TS 802H as aservice processor terminal to the TS 806/816, attach one end of an

YourTS 802H can be connected to an auxiliary serial printer to make apermanent hard copy of
data. The TS 802H's serial printer interface allows the TS 802H
to be used with most RS232-
compatible serial printers currently available on the market, including both character-by-
character and buffered printers. You can use a
dot matrix printer, ahighspeed line printer, or a
letter-quality printer. You may also connect amodem
to transmit data to another location.

2. INSPECTION AND INSTALLATION
The RS232C serial port labeled P2 is ready to use for aserial printer when the unit is shipped
from the factory. If this port and the otherRS232C port (labeled
P1) are both used with printers,
cut traces on the printed circuit board and install jumpers (as described
in Appendix I) before
attaching the RS232C interface cable.
Deviceassignments are given
in Appendix L; addresses for RS232C portsare given in Appendix
K.
The second diskette included with the TS 802H is labeled CBIOS. This diskette allows you to
modify the default printer device from one serial type to another or establish different power-up
default values. Instructions for modifying CBIOS are provided
in Appendix O.
2.4.7 Connecting aModem
You can connect one
or two modems to the TS 802H. The RS232C port which is labeled P1 is
ready to interface to amodem.
This port is controlled bydipswitches which allow the TS 802H
to be used with amodem or as a
terminal for aTS 806/816. Appendix Glists the switch settings which control this switch.
Toconnect
two modems to theTS 802H, cuttraces on the printed circuit board and install jump-
ers
in the pin connector of the port labeled P2(as described in Appendix I) before attaching the
RS232C interface cables.
2.4.8 Plugging in the TS 802H
Afteryou haveconnected the RS422 cable and
all RS232C serial devices, plug theTS 802H into
the wall outlet but
do not turn it on yet.
