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.

1.2 System UDit
The T11aa PLUS System Unit is composed of subunits. All
subunits of T11aa PLUS system are built in one compact System
Unit case. They are System PCB (Printed Circuit Board), 3.5"
FDD (Floppy Disk Drive), LCD (Liquid Crystal Display), Keyboard,
Power Supply Unit, Speaker and harnesses.
In a maintenance service, the faulty subunit will be replaced
with good spare subunits easily.
Followings are showing locations of subunits of the T110a PLUS

1.2.1 System PCB
System PCB is composed of processor (i80C86-2), RAM Memory
(256KB
for Main Memory, 32KB for Video RAM), ROM Memory· (32KB
for BIOS, 32KB for Character Generater of CRTC), FDD Controller,
Keyboard Controller, Display and Printer controller and Printer
Adaptor.
As the advanced technology, this PCB introduces four liGate
Array" packages .
The System PCB houses:
- Central Processor Unit (CPU: i80C86-2 compatible l6-bit
Processor. )
Clock speed is 4.77 MHz (Slow mode) or 7.16 MHz (Fast
mode) .
switching the clock speeds can be done by depressing some
keys of keyboard.
When the system power turns on, the processor runs at 7.16
MHz.
- Main Memory 256KB dynamic RAM (as standard configuration)
- PCB connector for additional Main Memory (from 256KB to
640KB)
Internal 384 KB memory expansion cards.(Option)
3Z KBy ±>~*c;
-BIOS ROM (256K-~j bes MASK ROM) including Initial
Reliability Test and Initial Program Loader.
Programmable Interrupt Controller (PIC: i8~C59A
compatible)
providing eight-level Interrupt Register/priority Logic,
Interrupt Mask and Vector Address
- Programmable Interval Timer (PIT: i82C53 compatible)
- Direct Memory Access Controller (DMAC; i82C37 compatible)
for Floppy Disk Controller, Hard Disk controller and
serial Input/Output operation. .
-
Floppy Disk Controller (FDC : TC 8565F compatible)
