Well, that's it's time to give
description and technical specifications of the most common
at the moment and a relatively
inexpensive models Amiga - AMIGA
1200. I'll note that this
text was in our newspaper AMIGA
INFO, but since this newspaper
died and this number is not at all
available, and should know about Amiga
all, that is the the text.

HEKOTORYE TECHNICAL
DATA COMPUTER
AMIGA 1200
CPU: Motorola 68020 14MHz
(Be careful, you can not
compared with pisyukovymi megahertz! Motorola processors have
better performance with identically clocked processors Intel.
At first AMIGA formula works great
multitasking, with no loss of quality music is played without
inhibition and twitching work any 2D-effects! And if you just
rasshirete memory, naked AMIGA will work in almost three times
faster!). Capacity data bus - 32 bits. Has 16
independent 32-bit registers.
In this case, each register has
properties of the battery (for
Spectrum), ie with each register can do all that
whatever. The processor is built on
CISC-architecture. In general, the documentation for the
processor company Motorola can be found in any
kizhke the computer MACINTOSH,
because they also put the same
processors.
ROM: 512K running AmigaOS, there is a possibility
substitution on the RAM (if
set accelerator). So
it is possible to replace the Berea
operating system without changing
ROM.
RAM: 2MB, on the bare AMIGA possible to install an additional
8MB, with an accelerator can be set up
128MB, though the theoretical limit
- 4GB.
AUDIO: Musical coprocessor
PAULA, which has four DMA-channel
8-bit or two to 14 bits. The number of tracks (music channels)
is not limited. There are a lot of hardware effects, such as
hardware notes, interpolation, smooth transition from the notes
on the note, Noise Reduction, etc. The maximum sampling rate -
60KHz (for comparison, CD playable with a sampling rate of
44.1KHz). To play music was not wasted
time - the presence of DMA-channels
allows you to play digitize samples without CPU.
VIDEO: maximum resolution of
TV or a monitor of
Spectrum - 1280x512. With SVGA-monitirom - 1280x1024. Color
Palette - 16.7 million colors
there is hardware support for image compression method, HAM
(Hold 'Modify). The presence of 2D-coprocessors that allow
moving sprites, imposing their
for OR, XOR, AND, etc. using a mask, draw lines, fill the
closed surface, move the rectangular side of the screen of any
size and much more. All this occurs without the direct
involvement of the CPU, it only sets the coordinates, sizes,
etc. So way to such familiar to all
things on which on the Spectrum
leaves almost all of the processor speed is not spent on AMIGA
almost nothing! The presence of a coprocessor called COPPER
allows you to display on the screen
Multiple Image Modes
at the same time, organize
Interrupt on any
points (!!!) screen and set
other useful things. There
the ability to synchronize the video controller from an
external source: this is an extremely useful for post
production. Graphic chipset called the AGA. There
hardware emulation ECS and OCS.
Support for PAL and NTSC.
HDD: IDE-controller hard drive
The accelerator has
Controller SCSI. AMIGA perfectly
understands the screws that are formatted for pisyuke, working
with them both with! CD-ROM is usually
connect the same here, although it is possible and
via PCMCIA.
FDD: DD 880KB or HD 1.76MB.
AMIGA understands pisyukovye drives formatted on
720/800 or 1.44. Drive
incorporated into the body.
SLOTS: connectors
printers, modems, external drives, PCMCIA, RGB, Video, BCH,
System connector
accelerator cards, etc.
AMIGA was originally designed as a true multi-tasking
and a multimedia computer,
Workbench otzhiraet virtually no memory and no evading insane
swap-file on the screw, in contrast from Windows95, which is
not enough eats all resources pisyuka so
yet there is so multi-tasking
works that can be said that
her there at all. By the way, pisyuk
has a single-tasking architecture
computer and multimedia, he
has never been so themselves
understand, at single-tasking typewriter multitasking
operate normally never
be.
Accelerators now for AMIGA
There are the following processors:
68030/50MHz (this is me), 68040/40MHz and 68060/50 and
66MHz. Quicken they are respectively 10, 30 and 50 times with
respect to the bare AMIGA 1200. On There are hardware
accelerator Clock (battery) connector for
SIMM72 for memory expansion,
panel under the math coprocessor (for 68030, on the other
processors, he built), the controller is SCSI. Processor
68060/50MHz works about 30% faster than PENTIUM 133, but
and is an accelerator it is not cheap - at least $ 570. From
May 97-th year will begin production on a PowerPC accelerator
for AMIGA 1200.
AMIGA works perfectly with the
networks such as Fido and
Internet. With the Amiga you can
easy "climb" on a variety of WWW-page, so now
popular on-chat-with o.s
people around the globe
find friends in Europe, America, Africa, etc., every day
Download "Freestuff" software, in general,
enjoy all the charms
modern technology.
And most importantly, on the Amiga
You never have to wait!
While running a program, you
can start another one and do
all you need! A work
on the Amiga can be at least two hundred programs
simultaneously! Multitasking RULEZ!
If you are interested AMIGA computer and you want to know
about It more or just want to
ask any questions,
can write to me at the address in
ZXNet: 095/401.5 or leave
text file with the issue (s)
on DITRONIK a BBS disk: C:
(490-70-44, daily from 23 to 8
hours). There you will find
many different and interesting
information on computer AMIGA,
software for it, etc.
