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.

1.3 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.
