Toshiba T1100 PLUS User manual

1.1 General
Toshiba TIIOO PLUS is a portable personal computer which is
compatible with IBM PC and is situated at higher rank of
portable computer than Toshiba TllOO. It provides many powerful
functions in spite of its compact size. Hardware of the TllOO
PLUS, most. of IC chips are,-f-MOS type so that the power
consumption is very little :;'0 V W) and Gate Array IC chips are
applied so that it is very mpact and light weight ( (:)
). J. 0-rr t;- 151/
The TllOO PLUS System has following two types.
1. F type - Only one Floppy Disk Drive.
2. F/F type - Two Floppy Disk Drives.
The TllOO PLUS is composed of System PCB, Keyboard, LCD, 3.5"
FDD (Floppy Disk Drive), Power Supply Unit and case. LCD can
display 640 X 200 pixels in graphic mode and 2000 characters in
character mode. The 3.5" FDD have capacity of 720KB.
The standerd memory size of the TllOO PLUS is 256.KS and it is
able to extend up to 640 KB with optional Memory Card.
Option unit to the TllOO PLUS System are one Memory Card (384
KB), Modem Card and Interface Card are capable to be installed
in the TllOO PLUS System Unit. The optional external unit
attached to the system unit are 5.25" External PDD 2D (Storage
capacity of 360 KB) and I/O Expansion Box are prepared.
The TllOO PLUS has connectors of Color/Monochrome CRT Display
port and RS232C port and Print r/FDD on the rear panel of the
TllOO PLUS.

1.3.1 Memory Expansion Card
The Expansion Memory unit is an option memory board to be
installed on the System PCB. It is installed to the TllOa PLUS
System Unit just by plugging in the connector on the System PCB
and expands the memory size of the TllOO PLUS system till 640KB
with the basic 384KB memory.
When the Expansion Memory Unit is installed, the Configuration
DIP Switch must be changed properly. (Refer to page 1-10)
WARNING
The Memory chip is very weak in a static electricity shock.
When you handle the Expansion Memory board itself, it is
recomended to protect the Expansion Memory Unit with anti
static electricity materials.

1.3.2 M.odem Expansion Card
The Expansion Modem Card is an option card which communicates
wi th an external asynchronous communications device through an
appropriate cable having modulatar jacks on both end. one end of
the cable is connected to the External Modem Card and other end
is to a wall jack of the telephone line.
It supports CCITT V. 22 asynchronous mode and BELL 2l2A. The
specifications of this card are as follows.

1.3.3 I/O Expansion Box and Interface Card
Expansion Box is an option unit to provide the I/O channel to
the TllOO PLUS System. This unit is composed of the Expansion
I/O Cable, Interface Card, Expansion Box and AC Power Cord. The
Expans ion Card, Backpanel Card and Power Supply are in the
Expansion Box. Adding an Expansion Box provides five expansion
slots.
An option adaptor in the Expansion Box and. the System Unit
communicates through the Interface and Expansion Cards. The
Interface Card is plugged into the EXP sockets at the rear of
System Unit. This card is connected to the Receiver Card in the
Expansion Box via a cable having 62-pin D-shell connectors at
the both ends. The Expansion Card is mounted one of six
Expansion Slots in the Expansion Box.
