Amiga - Description of the AMIGA 1200.

                AMIGO 1200


   The delivery Amiga 1200 include:
computer, power supply, mouse, connecting cable, two brochures, 
5 disks, additional instruction. 


   Left, at the bottom of the back plane
computers are jacks and connections.
Drive, as usual, is on the right
some angle to the lower plane
Corps. The keyboard is made in the system
DIN. The power supply has two cables to connect to the network 
and the computer and switch. Design your mouse more successful,

than in previous models, it is easier to
work and has two buttons. One user's manual contains 
information about computer, connect it, the technical

characteristics, description of findings, etc.
The second, more volume booklet contains
description of the operating system.


   In a separate package contains a floppy disk:
Amiga Workbench, Amiga Extras, Storage,
Locale, Amiga Fonts.


   Connecting a computer is made
using the appropriate cables and a monitor. On its screen after 
a while after the image appears

set of diskettes, falling into the drive. But
In fact, as in other computers
in the drive you can install only one
3.5-inch floppy disk. Pause also explains
the fact that the "reset" (default setting in
zero), the computer goes a little more
10 seconds. After pressing Ctrl + Amiga +
Amiga is about 1 sec., And 5 - 6
sec. screen darkens. At this time, the system
checks whether the card is not connected to PCMCIA.


   System Version 3.0 looks no different
from version 2.0, introduced only minor
changes, such as the attributes of top
part of the Workbench and in the image window
Workbench can work with any resolution and any number of colors 
except for the regimes and HAM HAM8. Additionally there is an 
opportunity to place graphics on the background of the "plane" 
Workbench and windows. When active, this gives 256 colors

very interesting effect.


   On a floppy Amiga Workbench except libraries, drivers and 
other necessary files MultiView is a program for displaying 
graphics, text and play samples. With this program you can

obtain an image in all modes of the Amiga. Interestingly, the 
graphics can be loaded onto a separate screen (screen) or in 
for this purpose by the window on the Workbench (Except for the 
regimes and HAM Ham8). 


   Amiga Extras diskette contains three main directory. The 
first - the program to determine the system configuration, and 
the definition graphics mode, the number of color settings for 
the printer, serial connection, the work of a mouse and 
keyboard to your own graphics in windows or development of 
sound to different operations. 


   The second directory is the program
Intellifont, with the help of a vector fonts, font, placed on a 
floppy disk Amiga Fonts you can get your own

fonts of different sizes.


   The third folder contains a program showing the 
configuration of your computer at the moment, and so-called 
commodities, ie resident programs, already known

users of version 2.0. Floppy Disk Storage
includes drivers for printers and monitors, keyboards, maps and 
files that connects additional logic devices, for example, 
resistant to "reset" (dumping) RAM-disk, the so-called tube 
(pipe) - Boolean device that allows you to transfer

information between different processors
(Task) Amiga without the use of such sophisticated techniques, 
such as language AREXX, and as a logical drive through which 
you can read floppy disks recorded in IBM format or Atari ST 
(Workbench 3.0 has a program CrossDos) as a resident program 
(commod.ty - they came with Kickstart and Workbench 2.0, they 
work after the inclusion of icons or every system startup 
floppy disk with this by placing them in a directory WbStartup),

after their launch in the format of an IBM or Atari
ST also work formatting program
and copying software.


   Locale is a diskette with all files
language versions of Workbench. You can select the language, 
country, system of money, time zone, the system records the 
date and from this time Workbench and all recorded in it

programs will be available to the user in
this standard.


   Floppy Disk Amiga Fonts contain both vector and standard 
fonts (Adobe). 


   Setup (configuration image
which appears on the screen after clicking
both mouse buttons during a reset) is
differs from an option in version 2.0. Except
select the device from which kicks off
system, there is a choice of
images (PAL / NTSC), how to use the memory, turn off the cache 
(cash - processor cache, and Motorola 68020

cache disk - improvised field of mass
or RAM) and the editorial board of connected devices (boards).


   Model 1200 has a processor Motorola
68,020 and is 32-bit computer.
Frequency oscillator is increased to
14 MHz. There are also new graphics LSI
AGA. Compared with previous models
programs such as, for example, Imagine
2.0, Page Stream 2.21, Vertex 3d Editor,
Cinemorph work almost five times
faster.


   In the Amiga 1200 can be displayed on the screen
graphics modes 2, 4, 8, 16, 32, 64,
128, 256, 4096, and 262,144 colors. Number
Color does not depend on the resolution, but it depends rather 
on the capabilities of the monitor, since, as the frequency 
images, it can be programmed. 


   Amiga has a range of 16.8 million colors
but the display can display only (!) 262
Thousands of colors. At a resolution
Super HIres Interlace on the screen can be
685,360 points, ie slightly more than two
times the possible number of colors.
Practically, this means that visually it makes no difference, 
because there are no graphics in which each color image 
repeated only once! 


   The work plan on the Amiga 1200 are of interest program 
Deluxe Paint 4.5, ImageFX, VDPaint, Scala MM300.



   Of the automatic modes can be called
Art Departament Professional, by
that can reformat the 24-bit image on the Amiga. Display
graphic representation is possible and with the new program 
Direstory Opus 2.4. 


   System version 3.0, except for recording and
playback systems, Fast File
System (FFS) and the Old File Sistems (OFS),
is the so-called Disk Cache. This gives
two new formats: DC-FFS and the DC-OFS. Disk
Cache does not use a floppy disk volume (FFS -
879 kB, OFS - 837 kB), and greatly accelerates the reading of 
the catalogs and job floppy at all. This format in earlier 
versions of the system is not working. 


   On the computer on his back
wall located next slot (right
left), a network socket TV (for connecting
TV) socket Composite Video, jack RGB / RGBI - for color 
monitors, two Audio jacks (left and right audio channels), 
parallel (printer, samplers, etc.) posledovalnoe connection 
(for modems, printers, MIDI and etc.), slot for additional 
drives, two nests - the port the mouse and joystick. At the 
bottom of the plane under the lid is a processor bus through 
which to computer can connect the processors of a higher class, 
emulators, other computers, memory, RAM, etc.



   On the left wall of the housing port is located
PCMCIA. It is intended primarily for
extensions of the RAM type FAST, maps ROM,
for connecting the controller and CD-ROM, if
need to switch modems.


   In the computer has a connection to
connect 2.5 inch hard disk
standard AT-BUS.


   Thus, compared with A500/A600/A2000
Amiga 1200 has the following advantages:
New graphics capabilities, the new operating system, work 
system in different language versions, an embedded controller

hard drive, a digital image output
- RGB, great expandability,
Despite the closure of the architecture (CPU-BUS,
PCMCIA).
