Tape
Unit
Printer
The 5100 computer is composed
of
a keyboard, a
display unit, a controller, storage, and
an
integral power
supply. The keyboard
and
the 5-inch
screen
are
the
interface between the
user
and
the controller. The display
adapter connects the display unit· (or
an
attached TV
monitor)
to
the controller. The base
I/O
connects the
controller
to
the keyboard and the internal tape unit, and
to
the attached
I/O
devices and features.
The computer uses the programming languages APL and
BASIC. Microprograms within read only storage and
programs that are loaded into
read/write
storage are
used
to
control the 5100 computing system.
The
input/output
devices include
an
internal tape unit, a
5103 printer, and a 5106 Auxiliary Tape Unit. There are
three features: the Serial
I/O
Adapter feature, the
Asynchronous Communications feature, and the
Katakana feature.
I/O
DEVICES
The
5103
Printer
The 5103 printer is a wire matrix printer used by the
5100 computing system. The 5103 printer provides a
hard copy
of
the data at a rate
of
80
characters per
second or 120 characters per second; For additional
details on the 5103 printer,
see
the IBM
5103
Printer
Maintenance Information Manual,
SY31-0414.
Theory
The
5106
Auxiliary
Tape
Unit
The 5106 Auxiliary Tape Unit attaches
to
the IBM 5100
Computer through the
I/O
channel. One 5106 auxiliary
tape unit can be attached
to
each 5100 computing
system. The 5106 auxiliary tape unit stores up
to
204K
bytes
of
data.
It
uses the same data cartridge and data
format
as
the internal tape unit
of
the 5100 computer.
FEATURES
Serial
I/O
Adapter
Feature
The Serial
I/O
Adapter feature allows the 5100
computing system
to
communicate with other devices
via a serial
I/O
bus. The user must load the controlling
microprogram into
read/write
storage.
Asynchronous
Communications
Feature
The Asynchronous Communications feature allows the
5100 computing system
to
act
as
a 2740 terminal and
to
communicate
with
remote systems. During
communications, the 5100 computer is dedicated and
cannot perform APL
or
BASIC operations. The user
must load the controlling microprogram into
read/write
storage.
